Many people report bugs with lists that turn out to be the “expected” behaviour - i.e. that Bubble lists don’t allow duplicates. Clearly deduping was not expected by a large number of users, like me, and nor should we expect it as it is completely counterintuitive.
The duplicates in a list - what I’ve found is that you can have duplicate numbers and texts in a list - if you use “set list”. I use it for holding scores, lists of email addresse etc where I want to hold duplicates. I’ve previously tried a lot of messy ways - eg storing a CSV string., storing JSON - very painful.
