Roads to Leningrad: Activation Markers not working + 4 missi

Hopefully, someone can help me here:

Two problems

  1. How do the German AM / German AM Pool and Soviet AM / Soviet AM Pool work?

I’ve tried dragging AMs from the counter manifest onto these windows, and don’t seem to see any way to actually use them. Even The “reshuffle” button doesn’t seem to cause any effect.

  1. I don’t see activation markers for the formations that are in play on the first first turn (both German and Soviet), but the the activation markers for later formations do show up among the pieces that arrive on later turns.

Any help would be appreciated.
