What would cause this weird bearing wear?

I'm by no means a pro engine builder but I'm thinking if your rotational clearance off the caps exceeds crank fore and aft motion, you're probably good.
Evidently you are not comfortable with the cap mismatches and I probably wouldn't be either.
Well, try to move one. On the #4 cap, it appears to hang over the block. I might try to reposition this one just to satisfy myself. Don't forget the assembly lube.

I talked to my engine guy and showed him pictures and doesnt really think its too big of a deal, he told me if I wanted I could loosen the caps off and try and position the caps better, but doesnt feel that there is anything to worry about. The caps cannot actually be flush on both sides anyways as they are all a bit smaller than the block or the bolts dont allow for it.

I pulled on off and took a look at the bearing and it still looks like I just put it in there, so I think I am just overthinking this...lol

And yup, using lots of the proper assembly lube!
