After importing a Nintex 2013 workflow it tells me in an create list item action that some list fields are write protected? We can then save the workflow, but it's not pssible to publish the workflow.

We tried to delete the list and create it from ground up, but no changes. If we delete the action and add the same action with the same configuration, it works fine.

Does anyboda had the same problem? Is this a workflow configuration error or is the list configuration wrong?
