Yeah, happened to mine and I'm in Scotland, not the hottest place! To be fair I only noticed cause I was looking to remove them and put decals on the tank instead so at least they came off easily
I waited a considerable time to collect these in person. Was concerned they may not fit within the white panel or cover the original script. They also had to be shaped after sitting in boiling water to the profile of the air-box as there was insufficient curvature in them. Also needed a medium with which to adhere them with. Does exactly as it says on the label.
