Can you add a screenshot of the Database that connected to the list? And I guess in the list you didn’t add the date from magic text? And I suggest to create a One to Many relationship to store who created adding Logged in user there instead of creating a text property to store who created.
You can hide the clicked item with grouping the components inside the list and add a visibility condition from All Logged in user’s > Reservations 2 count. You can add that same condition on the Create action too!
Most times when you simply copy a custom list, changes to it are synched across the copies, to solve this all u gotta do is change “What is this a list of” to a different collection and then revert to the original collection.
