I’m finding that having only 5 languages having English as default option in a-tisket’s language field leads certain users to not bother selecting the correct language using the release editor before submitting a release. This is an area where this (otherwise excellent) tool leads to lower data quality. I would either support the full list or just remove the field altogether and let users manually set the language using the release editor, or leave the field blank if in doubt.
Edit: Perhaps having “English” as default is more to blame than having a limited number of options. Amended my suggestion accordingly.
