When a patch has Filter 1 in use e.g. in Module 1, setting another filter module e.g. Module 2 to 'Filter 1', destroys the existing Filter 1 in Module 1. This existing filter may already be in use by the patch - all patch connections and settings are lost - no Undo!
Where I see it's not necessarily a bug, this seems like a super dangerous move with no turning back, and no warning is given that Filter 1 is already in use elsewhere.
I don't have a solution, but it might be good to have the used Filters greyed out/unavailable until they are disabled in their existing Module, or at least have some warning prompting - "Filter 1 in use! Proceed?"
i think this is across all the top panel modules. If you select one that's already in use it destroys the existing instance in another module slot.
