Unable to filter selection by family category

Hi,
I’d like my selection to be filtered by family category. In the example below, I’ve selected 3 elements in the model, one of which is a mech equip family. For some reason, I can’t filter out that mech equip family.

Try putting a ‘String from Object’ node between the Categories node and the ‘==’ node.

That was it! I had tried that earlier, but must have had something else wrong. Thank you!

Another option would be to use the ‘Equals’ node. That node will also check if the types are the same, whereas the ‘==’ does not.
