'Save Producer' button is missing when submitting a record producer
Any supported version
'Enable Wishlist' checkbox is unchecked for the Catalog in which the Record Producer is present
Setting 'Enable Wishlist' to true for the catalog resolves the issue.
If 'Enable Wishlist' is set to true and the 'Save Producer' is still not visible, check for the value of system property named 'glide.sc.producer.allow_wish_list'. This should be true.
