Opencart shipping extension must use taxed sub-total instead of non-taxed

Job ID: 40082473

Budget: $10 – $30 USD

I use Parcel Pro shipping method in my opencart 3.0.3.9 shops.
For every shipping option in Parcel Pro I can use 2 activation dependencies, sub-total and total weight. The sub-total field now uses the non-taxed sub-total.
We use different tax values in our shop, so if we want to give free shipping above €75 we have a problem if a customer buys items with different tax values.
The sub-total field must use the Taxed sub-total to set the activation dependency right.
Must be a small issue I think to point to another field.
I think it is in the file catalog/model/extension/shipping/parcel_pro.php
