None of the Three Marking Functions produce a check mark

[michaelkelly]

I have been deleting redundant files for a few hours and all has worked flawlessly.
I am working on currently selected row as I have been all morning.
I have been using the same search criteria all morning.
I clean out my deleted files after each scan and file delete process.
Just now I had a directory with about the same number of folders and files as earlier. (210 folders, 1400 files) duplicates detected.
I selected the Marking as "all but one file in each group selected"
NO MARKS APPEARED! I tried the other two options just to see what would happen, NO MARKS APPEARED.
I rebooted the machine and rescanned the file. None of the three Mark selections had any effect. Regardless of what I selected, NO MARKS APPEARED.
What could be the problem?

Thanks you, Mike
