Blue colored HQ Units in the Editor

[LordSAS]

In the editor some HQ units are blue in color and the "delay", entry into the game is set for turn 250 which is after the game ends. Are these from of past coding or are the units entered into the game due to some event trigger, like an army holed up in the Courland activates the Kurland HQ?

Disregard I found out what the colors mean by looking at the WiTW editor guide.
