Posts Block category filter not working

Hi, I noticed that the Post Block when has a category filter, the filter is not applied.

Example:

Filter applied to show only posts of a specific category https://imgur.com/a/FHxOHh3

In the editor the filter is applied ok (only one post has this categ) https://imgur.com/a/TW1C1UP

In the published page the filter is not applied (shows all the posts) https://imgur.com/a/zgB4yVt

I’m doing something wrong?

If not, I want to report this bug.

Thanks!
