Map details not presents at the start.

[colang]

Each time I open PlanGv3 I cannot see a lot of map details, VRP, VOR, little and medium airports, and so on.
Almost the same each time, sometime differents.
I can remedy deactivating and reactivating each category, and then I see correctly all details until I close PlanG.
It's not a great problem but it's a little annoying.
Is it known? If yes does exists a solution/workaround?
Have I to do some configuration (I studied manual but no ideas)?
