This is with Logos 28.2 on Windows 11
I can use the Concordance Tool to find verbs of a particular type - in this example Greek Nominative
But the options to filter further by either Number or Gender are greyed out (there are other similar greyed out sections but these two fitted in the same screenshot!)

The first occurence in the expanded list is plural and masculine so I expected to be able to filter by those (at least)

Am I misundestanding how this should work or is there something wrong with the Tool?
Thanks, Graham
