I put my OMP back on and I later noticed there was a gap on the top. Is this normal or something?

I thought I might have put it on wrong, but I'm pretty sure that's the only way I could have gone on. I didn't gouge it or anything.

I also don't think it would actually leak... I just don't like it or didn't notice it before.

 

It should be flush to the surface, is anything get in the way under it?

 

It is flush.

The gap seems to be because it's at the wrong angle or something (but how could that be?).

 

its supposed to be there. dont worry
