Using Server version of Jira Service Management in our own cloud environment.
We have issues with tabs in Screen setup, and in viewing issues, we get a tab when data is entered for any field of that tab (typically custom).
Up until yesterday, when we edited an issue the modal window would be tabbed.
Yesterday I added a couple of Requests with their own request type using the same issue type of existing requests.
Now, editing issues does not have tabs and I only found an Atlassian that said go to the request type and go to issue view and Issue view does not exist in any Request Type.
