Gooten Product Type won’t ‘stick’

Trying to select “Gooten Product” from Product Data dropdown, then publish the product or save it as a draft. The product is then listed as a Variable product and the options to choose which product are associated with Gooten doesn’t exist.

Aside from that major hurdle, I have kids t-shirts ages 2 – 12, which I can set up in Gooten as two separate print ready products, but I’m thinking that I’d need to have two different products on my store which isn’t ideal…that I could work around but the issue above is the biggie.
