Having entered the track titles and artist for every track in a release, I was not allowed to even submit it on the error that I hadn't entered the track titles and artist for every track. It also said I had not entered a complete artist credit, when I had entered an artist credit, without specifying what a "complete" artist credit is or how to enter it. I suspect the system by which artists are recognized is not registering my edits, preventing any information from being entered at all. A solution would be to get the system to either a) recognize added artists or b) not require artist fields, then once the information that is available has been submitted to allow for fixing those artist credits. That way the part involving the artist could be resolved later, without throwing out all the data and effort associated with it.
