Combining two % off discount codes - won't work with any minimum puchase parameters set. HELP!

I’m trying to create a combined discount of 10% off plus 100% off (free additional product).

It totally works with no minimum requirements set (minimum $, or min qty). You can place both items in the cart, apply both discount codes and it works.

The issue is - you can totally get the free item with the 100% discount code without getting the first item. That is why we need to see the minimum requirements. We want to set a min purchase requirement on that 100% code. It doesn’t work and the code fails.

(You can not combine a % discount with a buy x get Y discount. It has to be a % and % combo.)

Does anyone know how to solve this?
