MarketPress Network Activation causes Mini cart to display on other subsites

Hi WPMU,

WordPress: 4.5.3
MarketPress: version 3.1.1
Website: http://bluegemini.ca/store/

When I network activate the marketpress plugin my subsites get the Minicart displayed on some of there pages even though they aren't even set up with MarketPress.

Can this be fixed please? As a temporary fix I've disabled Network activation and subsites are on a site by site activation.

Thanks,

Tin
