Is this still the case after jumping to a new system, or docking at a new station? EDDI doesn't have information on the current system when it starts, you need to move for it to pick up the changed information.
Yes is still the case for me, for exempe i do some runs between TUN and ALRAI, in ALRAI I got all the information ( population, possition on dock pad ...) but for TUN it's tell me the system is unoccupied
