All the fields was created with the API, and I have created the "zrh" field using the GUI.
Then I try to submit such a form. If I try to submit say the "mcuploadeddataset" field (created with the API), the POST /submissions/v3/integration/submit/7748313/6c32dbf4-4649-4a3b-b262-527d862c11f1 request returns a correct 200 but in the contact information, I only see: "aevr aeefa submitted Test-7
No properties updated."
BUT if I submit the "zrh" field (created with the GUI), it works as excepted with the same POST request.
