Poster Frames not available for sequence publish in 2023.2?

There was a bug at one point and it was greyed out.

Poster Frame greyed out

Flame 2022.2, Poster Frame in Media Export is greyed out no matter what. I swear I used to be able to make an Export Preset to Jpeg using Frame 1 as Poster Frame…but on 2022.2 its greyed out? I swear this used to work in 2021.1 and 2021.2?

To be honest when that post popped up was the first time I had heard of the Poster Frame feature. Pretty cool.
