Surveyor problems

Lately I’ve ran into problems trying to adjust height on splines and track I will not let me hover over the height button on the advanced drop down bar using track but when I go to add a road or spline the advanced drop down bar seems not to exist as I will not let me click on it like it’s locked or something I’m using trainz 12 hotfix 4 any help is appreciated

I would run a database repair and see if that helps.

That's a weird unexplainable action.

I know it is driving me nuts because I love route building and this makes it harder and take longer but I will be sure to do that thanks
