We recently started shooting PCC10 in IDPA and the results page (MatchResultsCombined) on the iPad and iPhone display the division as “PC” instead of PCC10.
The Android tablets display it correctly as PCC10.
Damn. I don’t have ipad with me and it may take a while to get this changed on ios. So, just guessing… You could also try PCC_10 with underscore or “PCC TEN”.
