In cases where the ground is one faction and space is another, the editor defaults to the space faction who doesn't own the planet
Example: In Rimward, Nar Shaddaa is marked as Trade Fed in the GC editor

However in game Hutts actually control the planet, with a trade fed force blockading the planet
Same case for Ryndellia. Editor marks it as GAR, but Independent forces control it
