Options in cart for promotion items

Hi, I created a promotion where the customer gets a free product when their order total exceeds a certain amount. This free product has 2 options for them to choose from, but when testing it, the options aren't available for selection in the cart. They show up but are greyed out & defaulted to the first option variant.

Also I can't check Any option combinations

when adding my product to the promotion. Nothing happens when I click it.

there is a setting in the promo section to select allow for all combinations, cant remember where right now but its there,


found it, see image of add product in promotions window and see checkbox for allow combinations


I tried that before but it wont let me check it - I click & nothing happens.

Also when I select the product, the option fields don't highlight to use - they stay grayed out
