Switch Can't place new wallpaper on room dividing walls?

[Pink]

I love to decorate my house, but I came across a bug that prevents me from putting new wallpaper on walls that lead into another room (There's an attachment showing what I'm talking about, if you're confused). I can put wallpaper on walls normally, just not these connecting walls for some reason.

Device: Switch lite
Version: v1.6.15 build 13

You can't do it even if you stand beside the wall? On mobile the wallpaper on dividing walls can't be changed from the front, only from the side.

Wait, I didn't know that!
I've been trying to change them from the front this entire time. I'll try that and see if I still have the issue

Edit: Oh my god. Yep, It worked. I might just be a little bit stupid. LOL.
