Is the swap preview working for multiple target videos? Only seems to do one for me

[rmadmin90]

This as example:
you import 3 videos,
set a single input face,
set target face on each video.
Then enable / refresh "Face swap frames"

But only seems to preview the face swap on the first video that I've set the target face on

Am I doing something wrong, not understanding something, or is that just how it is currently?

EDIT: sorry idk what's wrong with me.
"select face selection for swapping" by default is set to first face. > change to all faces
