Redsec Battle Royale redeploy not counting

I'm not sure if it is a bug, or if the challenge descriptions are just wrong but:

Redeploying teammates in Battle Royale from redeploy stations does not register for the second treatment plant exploration challenge and for the third Battle Royale Specialist challenge. 

Redeploying from mobile redeploy beacons does count.

So either the registration of redeploys from redeploy stations is bugged, or the challenge description is misleading.
