Cannot search for non-mastered cards

Beastvold

Hello,

I'm trying to master my cards for white, but the filter selection for "Mastered Card / Non-Mastered Card" only allows you to search for mastered cards. I can't search for non-mastered cards. I've tried double-selecting the toggle, expecting the blue check mark to change to a red 'X' (or something similar). It looks like I can choose it only to be selected or not. Is there something I'm missing?

While it is nice to search for mastered cards just to see how far I've come, it isn't helpful at all when trying to build a deck working towards mastery. I have to flip through cards one by one with the zoomed in view to find cards that I haven't yet mastered. It is a bit tedious.

If this isn't a bug, and is "as designed" (I hope not!), the text should probably just read "Mastered Card" for the selection so users (like me) don't get confused.

Thanks!
