Columns not available for filtering

Hi, I’m using AP 5.5.1. I’m working on a Data App and I need to filter columns by two criteria.
This is my setup:

The output of the first widget is:

But when I try to configure the second widget there are only four columns to choose from:

All columns have values on them (no empty columns).

Any clues?

it was a problem with the domains of the columns

What happens if you remove the connection from the Refresh Button Widget to the second Nominal Row Filter Widget? That seems unnecessary, but I also don’t fully understand what you’re trying to do.
