Huh. Hopefully it is just a glitch (there have been a lot of glitches but most of these have been on the GMAT Prep side, not the actual GMAT).
I would suggest calling. Email support has been quite slow unfortunately. Moreover, the US has a long weekend - Labor Day which means gmac offices in the US are closed till Tue.
PS. I don’t think this means there is an issue with your score. Just the report generation seems to be off.
