Woocommerce 2.1.3 How to sort grouped products

So I guess nobody know how to do this. That sucks!!!

Put a number in the field at Product page / Advanced tab / Menu order. On mine I thought it wasn’t working at first until I realized the page was being cached.

Thanks for your comment but unfortunately that doesn’t work. Even with clearing my cache it doesn’t sort the grouped products. I was SO excited that you had solved my problems. Any other thoughts?

Thanks,
Matt
