Profiler error "The User is field is required."

Just purchased Profiler and get the following error when trying to upload a file to a user profile. " The User is field is required. "

Here is an overview of the code:

{{ profiler:edit_form files="true" }}
... multiple fields that works...
<div class="input-group">
                    <div class="input-group-prepend">
