No VNAV values in mcdu/flight plan-No checkpoints/arrows

As you can see I have no top of descent markers or top of climb

I know the constraints are there but there is no toc/tod markers

Please tell me if i can fix anything

I fixed it but by any chance would you be able to tell me why when I am in flight the constraint values move up or down in value. Like it is not showing the constraint instead it first shows Fl205 then goes to Fl 202 as flight continues, is there a way to see the proper constraint in mcdu without it changing?

if the constraint is not defined by a procedure or in the navdata -- then it's a calculated value that you'd be at for the required constraint on ur fpln

how to define in procedure or navdata?
