Huh? "Not a problem." I don't know how anyone can say that without first seeing where the hole is, how large, and how the exposed ramrod might interfere with the locks operation.
Maybe, you can fix the possible rubbing, maybe, it won't be a problem, but every time you pull the lock out you'll be looking at a hole that shouldn't be there. And so will anyone else that see's it.
Personally, I'd send it back, and moving beyond the PCBS, probably everyone else here would too because they wouldn't want any of their customers thinking that they'd made that mistake.
TOW is a good company that backs its products, and might well give you an upgrade in wood for your time and trouble.
