Shipping Price not calculated properly after shop update

Shipping Price not calculated properly after shop update

Hi,

I started using Joomshopping 3.3.0 a while back and also used the addon to calculate shipping prices per country per weight. This worked well. Recently I've upgraded the shop to the latest version (3.15.3) on my dev-plattform and the addon appears to be not working anymore. Instead the shop takes the basic shipping price.
I've tried re-installing the shipping_zip_weight_depend_1.0 addon but to no avail.

What can I do, besides not deploying 3.15.3 to my production site?
