Trouble with portfolio filters

Hello, I’m using the Stockholm theme.
I’ve created a portfolio page and designated which categories I’d like to show on the filter bar. However rather than only the categories I’ve designated, all are still showing on the filter bar. This is the page:

I would like to get rid of the filter category “semi-custom” on the line. What am I doing wrong?
