Part of the design of the system is that we track the User Perception of an issue (Type field on the Call Details Screen) as well as the Technical Perception(i.e. the actual Type Category it was found to be on resolution). The system does automatically populate the Call Closure Screen fields with the User Perception value, but you can change this. There is an additional Search Criteria field you can add when searching on Closed Calls called "Resolved Type" and this is the field on the Call Closure Screen. Note that this also applies to the Config Item field and the corresponding Call Close Screen Config Item Field is called "Solution Config Item".
