Citation X VNAV help

I cannot get VNAV to work. Flight plan is definitely configured correctly and altitude constraints are in the flight plan. PFD shows up with VNAV and even the pink path diamond shows up but the plane will not follow it. Anyone with similar problem? Maybe I’m doing something wrong but been trouble shooting for hours with no luck.

Are you dialing in a lower altitude so it will start descent?
