I had a similar issue trying to debug InlineModelFormsets. If the root cause is the same I have a PR open <https://github.com/django/django/pull/9320> to add documentation relating to how Inline Formets deal with prefixes.
Without knowing your specific circumstance it's impossible to know if this is the cause, but if so it was a pain point for me as well.
