I tried to make a backup of a Sharepoint-List with Acces and i created accidentally a new list in Sharepoint with the same URL, same ID and all the same data from the another one. Now if i create or delete an item in one of the lists it will be also created/deleted in the another one.
How can i delete the Mirror-list in Sharepoint? I need to delete one of them, because if not, i can not connect power BI with that list (Power BI show me the following error: The key matched more than one row in the table.)
URL of both lists:
i would be so thankful if someone can help me with that issue!
