I have been working on this problem and another that is not working right. As long as I could not get the night mode to work I was working with the map mode. I have an another post about that and I should consolidate it too one beings it looking like their connected with issues. While working the mapping program, all at once a screen I needed up, was gone. Working on it for hours and it used to work in the Mission setup but now it did not want to. The Polygon does. I thought I was reading someplace that they took the Mission rectangle setup out and use just the Polygon now. I need to find that again. So after a while I finally gave up and did a reset incase all my trying to get things working messed up something. After the reset and getting my setting plugged back in, the Night mode could be turned on again. Go figure. Have not heard back from support as to why I could not turn the function on. More testing today with the mapping. Suppose it could be a buggy R/C.
