Hello,
I am unable to edit the field "Dev team" (Drop down single choice) from Issue View Screen directly if some team name is already filled. But I can edit when it is 'None'.
When I edit the Issue I can able to change field value from existing to other value.
The same field is editable on other projects from view screen itself
I compared both the projects but i didn't find any clue.
Note: This field is added by custom plugin in our organization. When I verified all the configs are looks similar
