It appears that lists start with index number 0 on the Project Detail Page, but with 1 anywhere else (i.e. Preview, Live Test). This bug affects, and possibly breaks, all apps with lists on the Project Detail Page. I’ve made a couple of simple apps that showcase the bug (using S2P and DnD). Just open each app on the Project Detail Page and then remix it to see the difference:

- Index Bug (DnD): https://x.thunkable.com/projectPage/620241c39a3bd80010e2a2d6
