Note with multiple tags seems broken

[em020]

Note with multiple tags seems broken: when I was using a previous version of TagFolder(I don't remember which it was, maybe a pretty old one), note with multiple tags works fine, by fine I mean I can see the note in each tag folder, but now after I updated this plugin to the newest version, the notes with multiple tags only shows in one of the tag folders, and doesn't seem to have an obvious rule of which tag foler it will be in.
