Components have extra pin

I was using the "Check Pin Numbers" tool while verifying my BID-WID diagrams, and I noticed that every one of my components has one extra pin (according to the tool, anyway). 

All of these components are made with a variable group connector and datatables, and each one only shows 6 pins. I've checked their properties, tried selecting children, and using the reorder members tool to make sure none were hidden or disabled. 

The only thing I can think of is that Schematics is counting the Block Port as an additional pin on each component. I don't think this will stop me from exporting but it is a bit confusing. 

Should I just ignore it, or is there an easy fix?
