Finding the right node

Trying to build a selection set filtering for areas. The one I have works flawlessly on a test project except for 1 single floor.
Looking into the Dynamo script I’m seeing outputs I wouldn’t expect, which leads me to think I need a different node for Family.types.
I just want to filter my selection to only grab “Areas”.

“Area” is getting filtered by my mask, which according to the lists it shouldn’t be. OFFICE150 is an AREA NAME

Found what I needed to make it work. Still bugs me the first screenshot failed. It doesn’t make sense L01 areas being filtered.

Have you tried the OOTB “Element.ElementType” node ?
