Wrap up step on support workflow doesn't accept studio's bug as valid URL, when setting "Confirmed Bug" as resolution

On "Wrap Up" step on the support workflow, if you choose "Confirmed Bug" as a Resolution, a warning message is shown saying "Resolution indicates that this is related to a bug or feature request, but no URL has been entered in the Issue URL(s) field".
I entered a Studio's bug and the warning is still being showed up.
