Erroneous warning of groups that have all copies marked

[punar]

I get a warning that 6 groups have all copies of duplicate files marked.
But when I click the View button, there is nothing found.

After scanning through the disk, I had 6 duplicate folders that I deleted first (I manually selected the 6 folders I didn't want from the 12 shown).
After deleting the 6 duplicate folders I used the selection assistant to select files.
When I clicked the Delete tab I got the warning, upon which I decided to do a rescan and not risk anything.

This is possibly due to a small bug with filtering the duplicate view from another tab after the program has been closed and re-opened.

-put the program onto removal tab (not duplicate view)
-close program
-re-open
-Don't open duplicate files tab. Click 'view' button on warning in Removal tab
-'All copies marked' filter isn't applied. (to correctly apply it. select the filter from the Filters menu).
