Shipping fails to get billed with this plugin

Hello,

All of my customers paying with this Bambora plugin get accidentally a free shipping, i.e. the shipping method doesn’t get selected at all. This is quite annoying and it’s costing me money daily, since I don’t want to cause inconvenience to my customers by asking for the missed shipping fee separately afterwards.

No other payment plugin in use (Verifone, Stripe, Svea) fails to include shipping, so the issue must be in Bambora’s plugin. I’m using Tyche Softwares Custom Shipping Methods.

Can you provide help with this issue?
