The issue occurs when editing an existing application by assigning a new API... the current plan of the newly added API shows as "Sandbox" even though that plan was removed and the only one available is Bronze.
When you save it... then go to "Edit" to view it... it does show correctly.
Just so you know that "Sandbox" is not there... the screen shot of the API Plans...
Any idea where the "Sandbox" is being referenced from?
Thanks!
