Dear @Almotasem,
Sorry to hear you’re experiencing this issue. In the first instance, you can check out this post on troubleshooting invalid records to see what might be causing the records to be flagged as invalid: Troubleshooting Invalid Records
If you still need support, I would advise you to flag this with your organization’s Technical Contact so that they can raise a ticket with our Helpdesk. Our support team will then take a closer look at your specific implementation and can provide a more targeted response from there.
