Odd UPG after category enforced race

B rider according to ZP. Entered as C to a cat enforcement event, because I was allowed. I was filtered from results due to UPG. What the heck is going on?

A few races with incorrect settings seem to creep through the cracks, though a few organisers set the ZP settings that way. Makes for confusing Cat racing when it’s on purpose. With a 3R event, I’d suggest its setup issue but who knows these days.

If I do a CE race, I ignore ZP results.
