Situation:
I made a new request type, and based it on a wrong issue type, by mistake.
Now three Issues have been submitted, and needs to be moved to my new request type (based on the correct issue type).
Issue:
When using bulk change I cannot change the Request Type of these three Issues.
I can only change the Issue Type.
When moving Issues I also cannot change the request type.
Result:
I now have a request type I cannot delete without also deleting the Issues associated with it.
