[itsm] Cannot set Service or SLA in Activity Dialog (otrs 3.3.4)

Hello, I have been working on some process and I have an activtiy where the user can update some fields (Category, priority, Service and SLA) but when we try to execute this activity we get an error that says "Permission denied on TicketID: 103226!" and says Cannot Set ServiceID on TicketID 103226 I do have all the permissions on the group. Has anyone go through this?
