I’m realising just now that my point below was posted only in the other thread, so I will bring it up here too as I still run into this issue regularly.
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 just remove the field altogether and let users manually set the language using the release editor, or leave the field blank if in doubt.
