You don’t really mean to delete the Cart Items, do you? Attaching the Cart Items to the order doesn’t move them, it simply attaches a reference to the specific Cart Items to the “Purchase” item.
If you delete the Cart Item things, the list of Cart Items on the Purchase thing will disappear because they no longer exist in the database.
The list of Cart Items on the Purchase is just a list of references to the specific instances of the Cart Item datatype. They don’t get “copied” and now “live with” the Purchase.
You might want to go watch the first Bubble crash course video to understand the database (which is best thought of as storing objects of various types, and not being a collection of various “tables”).
