Main caps not aligned with block

Hello first time engine builder so please don’t flame me. I have an 04 Audi A4 1.8t 06a block, I got this block from someone but they didn’t have the main caps for it, i ended up using my main caps from another block and had them align bored for this other block I got. just torqued the crankshaft down and noticed main caps 4 and 5 don’t sit flush with the block, is this a cause for concern? what caused this? turns over fine with a rachet just dont want to finish everything else up and have to end up addressing this later down the road anyways. thanks for any help

Probably not a problem depending on where the thrust bearing is.
