Stuck with this tab?

[VM000]

When I go into experimental mode, everything loads fine, accept there is a certain tab that has the head "mods" and I cant close it, and it blocks my view of the actual world, any idea on how to fix it?

Uninstall your mod loaders.

If that doesn't work completely delete everything in your worldbox file, then install the game.
