Two alerts for user deletion - a bug?

Hi.
The Deleted Users alert records every deletion twice - once as deletion, once as modification.
Enabling email notification for this alert sends 2 emails each time a user is deleted, one for each record, which is quite annoying.
See below:

Any way of preventing it from alerting twice?
Thanks in advance
