Weird blu color sometimes appearing in gradient.

So after export i noticed some weird colors in a transparant part of my AE animtation inside premiere. I exported with luma and alpha layer and quiktime. The weird thing is i re exported all of the animations and exported the video again and the lines where gone. But a few days later i open the project and here they are again. This is 100% with the new exports and not the old ones. Can anyone tell how i get rid of this bug? Using after effects 2022 and premiere 2024.
