Dear Tristan Fareel (VUNHST - Digital Services)
Good day! Thank you for posting to Microsoft Community. I am happy to help you
I didn't experience the same situation in my tests.
To further troubleshoot this phenomenon, I want to confirm if this phenomenon is happening in multiple Lists? This phenomenon occurs only if it is a specific list, and you try to move the data to a new list.
If this phenomenon occurs in multiple lists, it is possible that there is a problem on the server side, I kindly recommended you can raise a service request in Microsoft 365 admin center, which the support there has the related permission and resource to help you check from the backend
Thanks for your cooperation.
Sincerely,
Tin | Microsoft Community Moderator
