Salmon elk zone

In the 2015 big game regs the general B tag in the salmon zone is capped for 2,507 tags but when I went online to purchase one it said sold out at 1,589 why is this?
The number of tags available listed in the big game rules booklet is the total number of tags available for that zone. The number of tags is distributed between three groups based on historical sales at the time the zone was capped. The rules for allocating the number of tags available can be found at in section 505. For the Salmon B tags, the quota for residents is 1,589 tags, the quota for nonresident is 830 and the quota for outfitters is 88.
