[bug] Campaign planet with Arhe Gekkar Field don't protect systems from assault

Hello, I'm playing Necron campaign, I've got world with Archeo Gellar Field, that by description should forbid invasion on system, and to connected systems. on lvl 2. I've got evel 2 of a planet, but Imperium is able to invade me!!!
Description says that only Aeldari are able to attack.

Personally I have no problem repeeling attacks, but If game sates it should work -- then it should work, or replace that Attribute with one generating money, I would be more pleased with extra +60 cash/turn instead of not working anti-warp shield.
