Power armor bug (Fallout 4)

Everything was always normal, but now from some point in the game the power armor began to "roll back". Or rather the frame itself.
I'd better give an example. Here I have T45 power armor. I can modify it, fix it and so on. But as soon as I get out of it and leave the location, then upon my return I find it in the form in which it spawned once in the world. If you hang other elements on this frame, then upon return they will be replaced by T45 and will be in the inventory of this armor. Another example: I walked in Danse's power armor from the moment I received it until the very end of the game. Then he repainted it as a guard, received a helmet and a breastplate for a quest and replaced them in the armor of Dance (sold the helmet and breastplate). Then he left the armor and went about business. He returned, and in the inventory of armor there is a T60 helmet and a T60 breastplate that Danse once had. Plus, the arms and legs now have a paladin coloration again .. In short, the armor rolled back to that state,
