Never Mind...
I think it was a conflict with another plugin.

Hi

Presale Question:

When you edit a design in the nb-designer (front-end) and want to change a woocommerce variation afterwards, it sets back your edited design to the default design.

Is it possible to prevent this to happen and keep your edited design when change variations?

(Especially since you have the possibility to assign your individual designs to every variation in the back-end... if you wanted to do that on purpose...)
