wiper (flap) seal won't flip over completely on slide

Yah, I have the same thing...

I asked dealer and he noted it's a common issue and that there is an Inner seal behind to keep stuff/rain out, but I agree, looks a little disturbing.. I tried to pull it out, but top corner is a little tough. Tried some slippery stuff, didn't help much. I think if I can get the corner pulled out, it might work.. dunno...
Standing by for additional solutions..
