Hi @dglite! I’m not sure I completely follow. Shipping classes can be assigned to a product, but it shouldn’t show multiple shipping classes on checkout. It actually shouldn’t show any shipping classes on the front end at all, as these are internal assignments that only show on the back end. It should only show shipping methods on the front end.
For more information, see our documentation on shipping classes and shipping zones
if you’re still having trouble, can you please post screenshots of:
1. Your shipping zones (WooCommerce > Settings > Shipping in your dashboard)
2. Your shipping methods within your main shipping zone (so, after step one, click on one of the shipping zones to show the shipping methods for it)
3. Your shipping classes (WooCommerce > Settings > Shipping > Shipping Classes)
4. The shipping settings for the product you were testing with (Products > click on product > go to the shipping tab in the product data)
5. What you see when you try to check out where it shows multiple shipping classes
