We have a Customer Service project in Jira Service Management project that is used by our customers to open requests. We want to be able to use sub-tasks in this project.
I am able to create the sub-task without any issues, but when I try to edit some of its fields (from the Edit button), I am unable to do it, because the field Customer Request Type has no match.
I tried to see if I could change the parameters in the Field Configuration Scheme, but it is not allowed for this field.

Any ideas on how I can succesfully edit a sub-task in a Customer Service project?
