WCM interferes with shipping calculator at checkout

Hello,
About the shipping calculator not automatically refreshed when the shipping zip code is updated.

I’ve done some tests again and it’s worst than I thought.
1/ The shipping calculator is not refreshed automatically when the user changes the delivery zip code
2/ When the user force the refresh by switching the country to an other then switching again to the good one, I noticed that the shipping cost is based on the invoicing zip code and not the shipping zip code! Which is a real problem.

When I deactivate the plugin, everything is back to normal.

Can these problem be fixed please?

thank you.
