What would cause this weird bearing wear?

Just kinda an update.

The clearances were measured at the machine shop, everything was cleaned meticulously as well. I began assembly of the short block, and used some proper assembly lube on the bearings. I installed the crank and put the caps on and set the thrust bearing. (Measured crank end play too and it is within spec). Made sure the crank turned easily after torquing each main. Once they were all torqued the crank spun really nice (thick bearing lube made it more difficult, but spun easily with one hand). I then installed the rods/Pistons and torqued everything down, engine still spins nice, turns nice with a smaller wrench, then checked rod side clearance.

As far as I know I've checked everything, and so far it's all where is should be.

But today I was looking at the bottom end and looked at the main caps. Some don't sit flush with the block, like one side I can catch my finger nail while I can't on the other, some seem almost "crooked" one side has a larger lip than the other. Caps are the right way, and in right order, also same bolts as before. I looked at the thrust bearing and it looks like it's perfectly flush on both sides. The caps fit super snug in the block registers so there is no wiggle room to make the cap crooked. Would this just be the factory tolerances in the caps? The block was line honed when I first rebuilt it and the mains were good (was even written on the block that they were). Just wondering if I somehow got them out of alignment when I put them on, when we were checking bearing clearances everything looked good with the bearings, I didn't notice the caps then, but also wasn't really looking.

Would this just be the factory tolerances in the cap to make them only fit one way? Or should I loosen the caps and try and line them up? When I installed them I just placed them on the journal, started the bolts by hand, and tapped the cap into place lightly with a rubber hammer, then torqued them, because I thought they line up automatically, could be wrong though.
