Looks to just be a via hole or something - the connectors only go in one way so you should be OK.

Yes, those are trace vias. They allow a trace to go from one side of the board to the other. Nothing goes in them, so just ignore them.

hey Chris,
don't feel bad about this one, when I first got mine, I was looking at it and thought there was an error, thinking "how could this be so, this is a mature product?"
It was only when I installed the connector that I realised they were vias. Nicely place in line with the connector pin holes.
