The mutator zone device is deletet but still blocking firing

Hi! I added the mutator zone device on my man in UEFN where I removed firing. But after I deleted it I still have this zone. I double-checked that it is deleted and double-checked if it is invisible.
Now I can say that there is no mutator zone device on my map but I still have places where players cannot fire.

Can I somehow clear the cache of all devices? To update it and remove zones where Players cannot fire?
