When note is tagged it is not seen in the tag's note list.

I've tagged 3 notes with the tag "fixeddate". As you can see on the left, fixeddate tag shows that there are three notes, but if you select that tag to see the list of notes, there is nothing.

Tried to restart application with no success. There are no such problems with old tagged notes.

Same issue here on 10.4.4 on Mac. I can see in the webversion that the tagging is working correctly, but the Mac application (and iOS app) seem to be showing this issue today. Stuff from yesterday appears to be tagged and filtering correctly.
