Perhaps there's a rule with a condition that matches your ticket status. You should take a look at every rules.
I don't know how many service you have in catalog, and if there's a lot of rules but you can use the "code" attribute of a service option in your event filter to avoid this kind of weird behavior where rules trigger when you don't want them to.
Service offering -> select your service -> definition -> click on the pencil relative to your option -> click on the pencil next to the name attribute -> Options -> Code.
You can use this code attribute to create event filter on your rules, something like ; rate_item_col = 0 AND status = 1214 AND status_old <> 1214 AND code LIKE 'W______O_D'
If you are already using this, and can't find a rule that matches what you are experiencing, i do not know what to say except open a ticket!
