Do all submissions show this or only some? When you tested your form draft, did you get all of the expected media? And now, when you download the ZIP for your submissions, is there media that you expect but is not in the zip? Do you expect more than 100mb of attachments to a single submission?

Thanks so much for those details. This looks like it could be related to this bug: https://github.com/enketo/enketo-express/issues/339

We believe it was fixed in Enketo 5.0.1. I see from your user agent string that you have Enketo 4.1.1 so the best way forward would be to get your Central server updated (taking care to back data up, announce a maintenance period, etc as described in the docs).
