The Data Packs button in the world creation disappears when you change the world type to Debug Mode, even if you can insert the data packs before changing the world type to debug mode.

What I expected to happen was....

When I switched the world type to Debug Mode the Data Packs button would remain

What actually happened was....

The Data Packs button is gone, but if data packs were put before changing the world type ,they still function

Steps to reproduce:

1. Get in the world creation menu
2. (Optional) Press the Data Packs button and drag and drop a data pack into the menu and confirm
3. Change the World Type from More World Options... to {{Debug Mode and press }}Done
4. → The Data Packs button is gone, even if the data packs in the debug mode world are still enabled when you enter the world
