HE vs AP tank fire

[pjbandit2003]

I am currently playing a long campaign as the Japanese. I have some Type 89 Yi-Go medium tanks with the 57mm Type 90 main gun with approx. 50 HE and 30 AP rounds basic loadout. The problem I have is that they will not fire the AP rounds. They consistently fire HE even at the FT-17 TG tanks of the Chinese at 50, 100, and even 150 meters. Is this a something normal or what. It is really aggravating to keep hitting these tanks with HE and getting a pen of 0 or 1 when the armor is 2 or 3. It does suppress them but it should blow them to pieces. Can anyone expand on this?

Thanks

Ken
