Hi,
On some projects, I can change the Issue owner simply on the Issue main screen. But in other projects, I can only do the same, through the "Assign" button, which opens a secondary screen.
Change of owner in main screen( See "Click to edit"):

Only through the "Assign" button(Assign button only):

I already checked my permission schemes, I did not see anything relevant.
The only difference is that one of the projects(ANX) uses "Issue security scheme" and another does not.
Any suggestion ?
