I'm not staff but I did take a look and see. The trigger seems to be in order:

But if you notice, the order to the Italian army is just to "Defend Hex" which is pointing to just inside the Greek border. So they are not in attack mode, really, and that is counter to the impression that is given by the objective text "Cutting off the supply route of the Greek First Army in Albania will allow the Italian Army to advance into Greece" and the popup message "Greek forces in Albania have been forced to a halt with the appearance of German forces in their rear. As the talks of their surrender begin, the Italians have renewed their own offensive."
So it's not a glitch or bug, I don't think, but an oversight in design. Or maybe it was intentional, given the popular perception of Italian army performance in WWII. This could be the designer's concept of an Italian "offensive."
