Strange Filter Behavior

[George Koulomzin]

I'm not sure, but here is a thought. Consider this hierarchy:

root
     A
         B
         C

In settings, make DK write to sidecar files in all cases.  If you select 
an image and click a tags check mark at level "B", and then synchronize, 
inspection of the sidecar shows DK created tag "A" *and tag "*A/B".  If 
you remove the check mark from "A", the tag "A" is removed, but tag 
"A/B" is not.  To DK, the */entire path/* is the tag.  If, in the 11 
files that did not work, there is not a tag for each level of the path 
from root to leaf, you would get the behavior you observe.
