I've migrated all company jira data to another new account company, because now it's a new separated product, and I deleted all unrelated projects on that migration, and lefts just one project. And now the scrum view is broken (on source of migrations everything works ok).
When I try to edit an issue from Scrum status columns like move, change resume title, assigned user, etc, it's look has successful worked, but when wait some seconds it rollbacks.
I recorded an video to show it because it's unbeliveble:
