Hi @lukas22,
it doesn’t matter if both users have a wishlist created with the same name. Wishlist items will always be specific for each user, and no one can overwrite those items.
If you want to edit, delete or change the status of a wishlist, please go to All Wishlist and view the wishlist in the front end, and you can control the setting here. Kindly follow the screenshots:

Please note that if you can’t see the delete option of a wishlist, it’s default and the setting uses the wishlist ID. If you want to change the default wishlist or delete the wishlist, go to Settings => General and remove the ID from the Default wishlist id option. Then you can delete the default wishlist.
