Filtering by Classification Attributes in 6WTs?

🟠Classification_Manager 

Hello guys!

I have created several classification attributes indicating the 6WT predicate, but when I do the search using the 6WT I cannot see these for filtering my search. Is there anything I am missing?

 

See the picture where I set the Predicate "Description" and to be display "Yes" in 6WTGs. None of my class attributes are then showing in the 6WT for using them as a fitler.

 

Thank you in advance!! ^^
