just to clarify, you are disabling routes after a router, not filters. And this looks like a bug or unintended circumstance, that is 100% reproducible. I suggest opening a ticket with Make support to forward it to the development team.
This looks like an editor issue rather than normal Make behavior. Filters are supposed to be enabled/disabled individually. First try a hard refresh, open the scenario in an incognito/private window, or clear browser cache. If it still happens, duplicate the scenario and test there. If the duplicate shows the same behavior, Iโd report it to Make support as a bug with your screenshots, because that is not expected behavior.
Yeah the browser doesnโt matter. I was able to replicate it and contacted the devs about it. They reported they are aware of the bug and working on a solution.
