Well what is the way to solve it @citynode?
Offhand, I would say that if you found any mobile-optimized theme that doesn't have the problem, even a mobile-only theme, then you could use that as your mobile option with Wordpress Mobile Pack.
Otherwise, you might be able to customize your primary theme so that it is at least mobile-responsive.
So you have multiple courses of action:
1. to make Woocommerce and a Woocommerce theme work well enough with mobile devices that Mobile Pack is not needed. I've had Woocommerce themes work fairly well with iPhone (the only mobile device I've tested) but was not using Mystile.
2. to find a secondary theme that Mobile Pack can use, that doesn't have the issues with variable items. This causes a doubled workload though, since now you have two themes that you need to maintain for one site.
