It's THEIR screwup, you're paid to review, not do the design.

Not crazy, just someone who knows what he's looking at. Kudos!
As others have stated, there's a whole number of reasons this could happen.
You can either reject the submittals outright (and make the designer
figure out where he/she went wrong), or spend the time to figure it
out yourself.
Either way, it's nice to see a plan reviewer pick-up on something like that.
