Course plotting issue

[Petrarca]

So hello there all
I've go Wolves of steel installed but I guess I've done something wrong and my sub isn't displaying so I can't really plot a course



And yes I've tried to do this but it doesn't work, as I can't check the box for some reason, it just says "disabled":



So yeah does anyone know what this issue depends on?
Also, sidequestion, is there a way to get back to the vanilla map I found it a bit comfier without all those squares. (I've also noticed that all european continental countries aren't coloured, they're just neutral beige. So no blue germany&italy and no red france.)
Sorry in advance if this was explained somewhere and I missed it.
