Campaign - Custom hide/show - Can't select flask as a class

[TerohsLab]

More of a filterblade issue it seems, but dont know where to report filterblade specific issues.

Ran into this issue trying to hide "Sacred Life" flasks. during campaign.

Hiding them via custom rules at the very bottom still works, but i would assume .. logically wise .. i would want to put them in the campaign filter section.

This is on a SC trade ubar strict preset with about 170 changes.
