"Other" rule cannot be selected

Hi! I searched the forums and couldn't find an answer to this. I've been trying to use the "Other" rule to key rules off of other file metadata, but when selected, the rule doesn't show any UI. The window flashes briefly and resets to the previously-selected rule. I've tried this on a few different folders, a new folder, folders with rules that are synced vs not, and the result is always the same. Is this a known bug or is there something I'm doing wrong?

Here's a screen recording via Google Drive of what I'm seeing: https://drive.google.com/file/d/1riydjFBODcj8d2WMuX-_h1xq-vty71P3/view?usp=share_link

What version of Hazel are you running?

Also, what you are referring to is an attribute, not a rule. Just to prevent confusion in the future.

Ahh okay, that's the problem. I was on 5.1, and "Check for Update" didn't catch the latest, so I've manually updated to 5.3.1 and it works. Thanks for the help!
