Scenes - Recall Filter

Hello,

I discovered a strange phenomenon, which unfortunately gave me a strong feedback.
I work a lot with effect scenes. I generally edited these scenes so that the recall filters only change the settings of the effect device. Everything else is blocked.
Now I recalled an ADT effect on a concert, and suddenly there was a loud feedback!
I later noticed that the recall filter of this scene was no longer correct, here the processings of some input channels were suddenly no longer blocked!
I definitely haven’t changed anything about this FX scene, how is it possible?

I have the impression that sometimes the recall filter settings are changed when I select another surface in the director, edit a scene, switch back to the original surface and then save this show.
Or it happens when I upload the scenes from another show.
The scenes always had an activated write protection, but I can’t say for sure.
It obviously(?) affects the processing of the channels, which are assigned to different inputs in different scenes (i.e. DX port or mixrack input).

now i check the recall filter of my effects before every show.
