Engine Cover Removal?

I screwed it right back in after removing the cover.

Anybody else have the situation where the little "cup" on the rear of the cover doesn't quite make it all the way to the little retainer bolted onto the back of the engine? It's no biggie, but I can tell they are supposed to interlock, but mine don't.

Mine doesn't "always" line up, I just install it as best I can and move on. It seems to stay in place pretty good whether it hooks or not.
