Think of it as two separate things: the physical navaid on the ground and the list of navaid frequencies stored in the FMC nav database.
Changing one will not change the other. If I knock down a VOR station tomorrow, it'll still be in the navigation database but that doesn't mean you're going to be able to tune in and receive anything! Likewise if I add a station to the navigation database which doesn't exist on the ground it might appear in the FMC with a frequency but if it's not physically there it's not going to be tunable.
In the case of FS, the actual navaids themselves are part of the scenery
. The default FS/P3D scenery is from c.2006 and between then and now many navaids have been built or decommissioned, frequencies have changed, new runways and whole airports have been built etc.
When you update your FMC navigation database with Navigraph you are updating the information on board the aircraft only
, not the actual navaids themselves which are part of the scenery. If the frequency has changed or a new navaid installed in real life that will be reflected in the up to date FMC data but unless you have modified/updated the scenery the aircraft will not receive a signal as there is nothing to receive!
To update the navaids in the sim there is a free package at https://aero.sors.fr/navaids3.html
For airport stuff like ILS etc you generally will need to update the airport scenery. Are you using default scenery or have you got addon scenery installed?
