Elk Tag Quotas

Why does the number of Non-Resident elk tags available for the Lolo, Selway, and Middle Fork Zones exceed the actual quota?

On the website showing the available non-resident tags by elk zone, the number of available tags (in the right hand column) exceeds the alloted quota for non-residents.

Why is this? Shouldn't this number be less than or equal to the quota, differing by the number of non-resident tags already purchased for each zone and hunt? This discrepancy seems to only affect the A and B hunts for the Lolo, Selway, and Middle Fork Zones.
