Display a subset of all categories, in a pro gallery

Question:
I would like to display a list of 10 product categories, out of the hundreds in my store. I am using a pro-gallery and have connected it to the “Collections” dataset in the CMS.

But I cannot work out how to filter out the 10 categories that I want to show.

I have tried the ‘filter’ but that seems to be an ‘and’ filter, so no categories end up being displayed if I create multiple filters.

I thought this would be simple, so I suspect I’m missing something obvious.

Help appreciated.
