Every User Uploaded is Admininstrator

Hi there

I have been using the plugin for over a year, it is great. However, since the start of 2024 we have had reports (and have now verified) that every upload is adding the user as administrator, regardless of which role is assigned.

For clarity, we use Members by Memberpress for roles, and are on the latest versions of both plugins.

If you can let me know what might be causing this, that would be great.
