This probably has to do with how the magazine business works.
Basically, for audited publications (such as CoDe Magazine), the audit rules say that one can count a subscriber as a fully qualified, audited subscriber for 6 months after the expiration of the subscription (assuming they keep sending you a magazine). And if you paid the subscription for an entire year and then cancel 2 months into the subscription but do not get your money back, then the subscription will count for the entire subscription duration + 6 months after.
Neither FoxTalk nor Advisor are audited. Generally, unaudited magazines try to follow similar rules, but they stretch things a lot. So it isn't uncommon to count subscribers (and keep fulfilling) for a year after expiration and longer. And in the case of magazines that already have a shrinking circulation, they push it even further of course.
So that is probably part of what you are seeing here. Another part could be a bad database :-)
