Unable to add smart filter (Glyphs 4)

Hey!

In Glyphs 4.0.1 (4004), I can’t add a Smart Filter, List Filter or Folder. This probably happened after I deleted all the default Filters. Any ideas on how to sort this out?

Thank you in advance!

At what point does the issue occur? Can you open the menu when clicking the :actions: button next to the Filter heading? Can you click on the Smart/List/Group filter items in the menu?

Yes, it works. The window for creating the filter opens as normal, but when I create the Smart Filter by clicking “OK”, the window closes without adding the filter to the toolbar.
