Recently, we migrated to sharepoint cloud and new records were created in sharepoint. However, few records show the date as 1/2/2023. When I tried to delete this from sharepoint, the list is not getting updated. Also, in the version history, I can see that one version shows that these dates were updated however the owner of the version is Service Nintex. I tried to delete this version, but not successful over there as well. Can anyone help that how can I remove these dates and service nintex version from version history?

Regards
