Dear Robert H Snow,
Good day! Thank you for posting to Microsoft Community. We are happy to help you.
We've done a quick test with OneNote for M365 with the latest version 2411, and we can reproduce the behavior on our side, paste only works when the column in the table is the same as the one to be pasted.
For the situation you have encountered, we do understand the inconvenience caused and feel very sorry for it. Please comprehend that Microsoft Support agents doesn’t have any access to the development related resource and don’t have any control on the development related scenarios. And we have not found related official artilce or planned fix in Microsoft 365 Roadmap | Microsoft 365 during our search currently, more resources need to be inolved in to help further.
Due to this situation, please contact your Microsoft 365 administrator, follow steps in this article to contact Microsoft related team. The support team has higher permission to directly assist you. The support engineers there have the correct escalation channel, and this is the most efficient way to report the behavior with the product team, they can involve more resources to confirm the if there's any fix release ETA further. This would be the most efficient way in handling this case for you.
Sorry for the inconvenience again. Your patience and understanding are highly appreciated. Hope you stay safe and healthy.
