Background setting in multi-monitor setup with --randomize misbehaving

[LisandraBrave]

I have a three monitor setup. Monitor 0 and 1 are both 16:9 aspect ratio screens, while monitor 2 is a 9:16 orientation. I have
feh --no-fehbg --bg-fill --randomize ~/.wallpaper/ ~/.wallpaper/ ~/.wallpaper2/
as my command.
The expected output is screens 0 and 1 having a random image from ~/.wallpaper/ and on screen 2, a random image from ~/.wallpaper2/
However the actual output is that every screen has a background randomly chosen from either folder.
In the case that this is a wontfix, is there some way to not have --xinerama-index blank the other screens
