User can register without completing fields.

I am using the additional fields plugin, where the user needs to attach some documents to register.

In one case, the user can submit the registration without attaching these documents. I have set the fields as mandatory. However, when he does not add the documents, he is redirected to an error page, although his registration has already been completed.

As a result, he goes without a membership level. In other cases, he does not attach these documents and leaves with a membership level that is the free level, the only level I am using in my tool.
