Hi everybody,
I want to delete all unused screens of my JIRA-instance. Although they are not assigned to any screen scheme and they are not used as a transition screen, there are some screens without a delete button.
Curiously, there is a strange bullet point without any connection to a scheme in the connected screen scheme column in the respective screen row (see screenshot below).

Moreover, I´ve queried all unused screens from the database (screens without screen schemes minus all screens, which are used in jira.fieldscreen in the descriptor xml of the workflows). The result contains the respective indelible screens. Thus, they actually should be deletable.
I´ve already deleted unused screen schemes, workflows, etc. without any problems.
Has anybody an idea what may be the problem and how to fix it?
Thank you in advance for your support.
Best regards
Dennis
