Hi @maggib,
I found the duplicate that i have highlighted with yellow and marked the font with red within list_name lf3sx85 whose name prefer_not_to_answer is seen repeated twice within list_name lf3sx85. For your ease check row number 89 and 93 under choices tab.

The principle behind this is that each list_name should have unique code under it’s associated name.
e.g. this is not allowed …
| list_name | name |
|---|---|
| test | a |
| test | a |
| test | a |
… but this is allowed …
| list_name | name |
|---|---|
| test | a |
| test | b |
| test | c |
If this is maintained you should not have to see this error message again.
Have a great day!
