Hi mnormand-
When I go to the lister page, to the shipping section and click on calculated shipping, the shipping insurance section is still there with the drop down for Required, Optional, etc...
Is it because you can't enter the shipping insurance amount like you can with fixed rate shipping? When using calculated shipping the shipping insurance essentially becomes calculated as well. Once the item is purchased and the shipping is figured out, the shipping insurance will be figured out as well.
I hope that helps!
