The transmission of the delete message is by design and happens according to the decaying transmission rate algorithm. Just as with all messages and object transmission, the point is to repeatedly transmit the information so that all conforming APRS clients can receive it (even if they only just turned on), but to decrease the frequency over time when the information isn't changing.
The fact that aprs.fi doesn't delete the object when it receives a delete message is the problem.
