I don't understand why my 8th Pzd wasn't activated during this battle

8th pzd was 2 hexes from the battle

His commander, 2 hexes above

And the Army commander

Above are Von Kluge Ini 8, and Halder OKH Ini 6
What was the probability of non activating the reserve?
Should I disband LVI th corps?
Change OKH commander? Unfortunately Guderian is KIA
Place the Pzds under direct command of OKH (with Manstein or Model) and placing OKH close to the front?
