Unable to unlock rewards vehicles

What gives?

I installed Company of Heroes "New Steam Version" on Steam, then installed the Eastern Front patch on top of it, as instructed. However, when I go to the vehicle section of the "rewards" tab, I only see the vanilla CoH rewards there. I don't see the options for the two new factions, or the mod-specific unlocks.

I own Company of Heroes and Opposing Fronts, I do not own Tales of Valor. Could that be why?

Currently only PE, Brits, US and Wehr received additional reward units. The Soviet/Ostheer reward units were removed some time ago.
