Existing Item Import Fine But Not New Item

Hello, testing with CSV import, when I import into existing items, all is fine and well, all properties & data etc are imported but as I found out, importing into existing item will not delete once updated so I did new import into “New Item”, the issue is, it only creates one post and just keep updating the same one post for all items, it does not create a new item for each record.

I know its not the file because it works fine importing into an Existing Item just not New Item..

Any suggestions? Thank You
