Clearing custom filter doesn’t work

When adding a new filter for ‘product category’, it filters correctly.
But clicking the ‘X’ doesn’t remove the filter. And also selecting to add a ‘Clear’ button (in the filter settings) doesn’t actually show a clear button.
For the default available filters though, clicking ‘X’ + the ‘Clear’ button work (price, review). So the issue is only for a newly created filter.
Any suggestions how to make this one work?
