If a Shopify order contains a non-shipable product add-on (like engraving or gift wrap) the App doesn't update the order status to fulfilled when the label is printed. Which it did previously.

Shopify handles these product enhancements as a non-standard temporary product which has no option to set a 'Product Location' or 'Requires Shipping' status.

I won't be the only person seeing certain orders not switch to being fulfilled when the label is printed.

The prior version just marked the shopify order fulfilled when the label was printed. You probably need an option to allow this or all these orders (about 20%) will need fulfilled manually.

I note other people have commented on the same issue for part-fulfilled orders? Maybe the same fix will cure both.

The system should probably ignore product type: mwproductoption (missing underscore between words on this).
