Which column is the 331 under? If its under "Current Usage", then that's correct.
The "Maximum Usage" would show "unlimited" if the Reseller has unlimited usage.
Also, don't confuse the Reseller limit with the User limit, as they can both be set for the same User, with different values:
CMD_RESELLER_STATS
CMD_USER_STATS?domain=domain.com
If this is a new box, the history files are not created until a reset happens on the 1st day of the month.
Eg: A new box does not yet have any history.
