I have this same problem. It's essentially making clicking on a tag useless as virtually no tags are set up like this.|
Personally I'd love the option (set in preferences) to set it up such that when I click a tag it automatically brings up a "ANY of these tags or sub tags" (using ANY logic, not ALL OF). But the way it works not is completely useless. I can't tell if it's a bug or just a strange UI decision.
EDIT:
This works well in the legacy version by the way: https://help.evernote.com/hc/en-us/articles/360052560314-Install-an-older-version-of-Evernote
That's what I'm going to use in the meantime.
