About old silent film "Ambitious Ethel"

A 1916 film has little info about it. It credits the cast as Ethel Burton and Oliver Hardy. I researched it and found this film was not one of Oliver Hardy's. He was on a different team. This film was a Pokes and Jabs film and Ethel Burton was a regular on the team. Cast should include Walter Stull and Bobby Burns as Pokes and Jabs and not Oliver Hardy at all. How can this be fixed?
