My graphics card is below spec, so I hesitate to post about a GUI issue, but here goes:
I'm on 1A, on a Huge map, the Korath currently have 3 discontiguous influence areas that I can see on the minimap, and it appears that 2 of those three might be continguous.
In the possibly-contiguous single zone, which includes the Korath homeworld, I see a both a cluster of undeveloped asteroids and an appropriately-colored group of asteroid fields that each show a mining base when selected.
Two asteroid fields in currently uninfluenced space are marked with Korath color.
In the definitely discontiguous space, I can see four mining bases at high zoom and when I point to or select the asteroid fields at icon-level zoom, but at the icon-level zoom they are colored as if there were no mining base.
