Broken vinyl on M5F90

Has anyone faced a similar problem and how did you solve it? The fact is that the right side of the M5 on which there is vinyl becomes almost the same color as the body, although the decals themselves are a completely different color. I checked and it doesn't depend on the specific machine (I bought a new M5 and there was the same bug). I tried to put other decals and change their color - the result is the same. If anyone knows how to solve this, I will be glad to hear from you
