Gamera High Vision Question

[Chrisdice]

Anybody with a Gamera High Vision or like cabinet (Popeye, Oni Musha ect.)
Behind the reel glass there is a plastic film. There seems to be an air bubble in between the glass and that film. Anybody else have this? Is there a way to remove it. I didn't want to take the whole thing apart untill I checked with you guys to see if this is common or if there is a quick fix. Its not hurting anything but I just like my games to be perfect.

Thanks

I have a gamera high vision...but I never took the front glass and panels out. Ive never seen an air bubble.
