Confusing and possibly bugged Achievement rewards

I have been playing for a couple of weeks regularly/daily (bored, waiting for college to re-start).

Yes! I have received some awards and continuing credit in certain categories.

BUT, I get zero credit for any of the "defeat X enemy units with units from the ______ tech branch", or "defeat X enemy units with ______ ."

As of the time I write this I have killed over 450 enemy units. Many of these by artillery and also many by armor.

Look at my Tactician and Ubersoldier categories.

Ubersoldier I have credit for defeating 282 enemy units FROM THEIR the infantry tech branch.

Tactician I have ZERO credit for defeating enemy units with units FROM MY infantry tech branch.

That is how it is in every category. I get ZERO credit for kills made by my _____ branch. I do get credit for kils made AGAINST their _____ branch.

Where are my rewards credits??? LOTS of missing gold here.
