Clarification on Score: Shouldn't an increased Q mean increased total?

Hi experts,

I gave 2 attempts on the GMAT in the same month and got a 710 on both attempts with the V-40, IR-5 and AWA-6 (and their respective percentiles) being the exactly same in both instances. However, my Q did increase from 47 (61%) to 49 (74%) in my second attempt. But despite this, my total score remained a 710 (90%) both times.

Can anyone please clarify if this is normal? Since typically one would expect their total score and their percentile to increase if they performed better and increased their quantitative score (with everything else remaining exactly the same).

I had sent this same query sometime back through the "contact us" option on mba.com as well, but have not received any response on it.

Thanks!
