Legendary seat covers wrinkles

I redid my 50/50 split bench with the Legendary kits. I am happy with them however there are wrinkles in the seat back on the side where the release button is to tilt the seat forward. It looks like when I tightened down the bezel it drawn it in where the switch is. I am reading that the wrinkles will eventually go away after sitting in the heat etc. But I was also thinking of removing the cover and putting one more layer of cotton filler on but i dont want to disassemble the seat and put more hog ring holes in it if this is a bad idea. I also have a heat gun I can attempt to treat the wrinkles with. Any suggestions?
