The filter does not appear for some categories

Hello!

My issue is, the plugin does not show filters for some categories, altough all of them are configured the same way.
It works fine on the main shop page ( https://bit.ly/3PmA12M ) and for most of the catgories (e.g. https://bit.ly/3AIoyGI ). By “working fine” I mean displaying attributes (search refine) under category in the right sidebar.

For two categories ( https://bit.ly/3c9cBQ3 and https://bit.ly/3ytqEHQ ) the filters are not visible (nothing is displayed). I checked settings and cannot find the problem – they seem to be set just the same way as the “working” ones.

Could you please help me?

Best regards
A.
