Problem with mulebuy shipping calculator - need help

I've been tracking mulebuy shipping calculator updates for the past 13 months, and here's what changed: - New interface rolled out about 3 weeks ago - Shipping options expanded to include 11 new carriers - Fee structure changed slightly (actually in our favor) - Response times improved significantly Overall, I'd say the platform is getting better. The shipping calculator functionality specifically has seen 28 updates based on user feedback. For anyone hesitant, I'd say give it a try with a small order first. That's what I did, and now I'm a regular user. Happy to answer questions in the comments.
