Cancelling or Sending a 2 on AP Physics C: Mechanics

Some of the colleges I'm applying to require that official AP scores be sent as part of their application. I got a 2 on APPC: Mech (I got a B+ in the class, and it was the first physics class I had ever taken; I have strong math grades and test scores otherwise).

I'm applying for math-related (not physics explicitly) majors at all these colleges. Their common data set says standardized test scores are "considered".

Should I cancel my APPC: Mech score to erase it from my AP records when I send it to these schools, or just keep it? I'm doing way better in APP: 2, and if I don't send the score, won't these colleges just assume I got a bad score anyway?
