Your files show the same pattern, I don't think its a random renaming with an underscore since it moved from one place to another. I'm betting your files actually are in the two different color spaces.

    Next test. I opened my two files in Nikon Capture nx-d. The image details show one file as srgb and the underscored file as adobe rgb. So it knows. Wondering if it knows because of the underscore, I went in and renamed the files. It still knows, so its coded in the file somehow. The moving of the underscore is just for our convenience.

    I would suggest to check your files and see if they are in different color spaces.

    Now after all this, I still can't wrap my head around color space. Apparently it doesn't matter to me how the camera is set. I shoot raw only. Its coded in the file, but I read its ignored by non-Nikon software for raw files. I have been exporting srgb in LR and not having any problems.
    You are correct.

    • sRGB files use: _DSC1234
    • aRGB files use: DSC_1234

    If you shoot raw, the color-profile you work in will be determined by your raw converter; in your case that's Lightroom, so your raw files will open using the ProPhoto color-profile (by default). When you're done processing the Export dialog in Lightroom will default to using the sRGB color-profile, but there's a drop down menu with a few other options:
    .....
    File order problem-lr-export.jpg


    Now, once you've converted a raw file to .jpg, that particular color-profile (or "color-space", if you prefer) is "baked in". I know you don't shoot .jpg BUT... If one day you were to shoot in, say, raw + .jpg for some reason the camera body will embed a color-profile (either sRGB or aRGB) into your .jpg's automatically because image files, like .jpg, require a color-profile.

    I know Photoshop will allow me to convert a .jpg from one color-profile to another but... 1) I can't imagine why I'd need, or even want to do that and, 2) I don't know if Lightroom allows you to do that or not, though I imagine it would.

    Re: File order problem

    I finally figured out the problem. Although I previously changed all my color space settings in camera to be Adobe RGB, I didn't save that change to the user settings for U1 and U2. So U1 and U2 were defaulting to sRGB. Now I changed them so all the files should display in order. Unfortunately it doesn't appear I can get rid of the underscore in front of the file names. That seems to be how Nikon (or Adobe) differentiates between sRGB and Adobe RGB.

    And to @Horoscope Fish - I open my NEF's with PCC which defaults to ACR. I changed my color space there to Adobe RGB so my files automatically open that way. I don't use Lightroom much since I prefer ACR. Thanks for the info!

    I stopped using my U's for important stuff. I always forget to save something. So I keep one set for basic shutter button focus in case I hand the camera to someone and the other U is just my everyday bbf settings that I'm very used to in case I need to take a quick shot when I'm not ready.

    That was my take too on the file names, you are stuck with the underscore unless you rename on import. It ended up being a good clue about your U settings though.

    Both U1 and U2 are set up for BBF. I rarely use BBF because it exacerbates my trigger thumb issue. But I leave them set that way for times such as this. I sat on a step up front when the acolytes, flag bearer, and bagpipe player entered. They were walking towards me so U1 with Aperture Priority, AF-C, and BBF was perfect (no flash allowed during Worship). U2 is set the same except it's Manual Mode instead of Aperture Priority. Thanks for pointing out the underscore. That was the key to identifying the file issue!
