New problem with Dark Eldar just cropped up

[Zarryiosiad]

Hi! After the most recent patch, Dark Eldar units that can choose either a Venom or a Raider as a transport, are automatically given BOTH vehicles. I can deselect one of the two options, but when I do the other immediately becomes greyed out, and can't be deselected, which means I'm stuck with a transport whether I want one or not.

The following units are not working properly:

Court of the Archon
Kabalite Warriors/Trueborn
Wyches/Hekatrix Bloodbrides
Grotesques
Incubi
Wracks
