Woocommerce Easyship shipping method cannot be disabled from a shipping zone.

For Woocommerce, one is supposed to be able to enable and disable Shipping Methods (Easyship being one such method) for each Shipping Zone. I’m currently finding that despite disabling (either disabling or not adding this method in the first place) the Easyship method for a particular Shipping Zone, the Easyship method still shows up in cart and checkout for that zone. Other people are having this issue too as reported here: https://wordpress.org/support/topic/can-we-disable-easyship-shipping-method-for-each-shipping-zone/#post-12661838.

As of now, the only way to hide the Easyship methods is to deactivate the plugin.

Please investigate and fix this bug.
