Z6III Cycle AF Area Mode in Video

[ckqualls]

First time I've tried video. I set Limit AF-Area mode selection to Single-point AF, Wide Area AF (S), Wide Area AF (L), 3D Tracking and Auto Area AF. I programmed Fn1 for Cycle AF-area mode. When I press Fn1 I can use Auto Area AF, Single point and something with in viewfinder a square with circle inside and a cross only.

Am I missing another step?

Thanks
