What I see on your screenshot:
The map is correctly displayed in the scene view, but not correctly in the game view.

Unfortunately I do not know what could be the problem.
I have not seen such a problem before.

If you send your scene (as a package) in support (support@infinity-code.com), I'll check it and say exactly what's wrong, and how to fix it.

In general, here are two main candidates to be the cause of the problem: camera settings and light settings.
But what exactly is wrong, it need to check.
