Flexiform node author

Hi, I just started using this great module. When I create a node using a Flexiform, the author is always anonymous. Even when logged in. It is worth mentioning that anonymous also have permission to create this content type. But the author is “anonymous” whether logged in or not.

If I expose the author field, it has the value 0 – even if I assign a default value.

How to fix this author issue?
