Variable products can not be added to a bundle

Hi @lucaskirby

Thank you for choosing our plugin.

We apologize for the inconvenience.

You should select a variation of the variable product as a default product if you would like to show it as a default product.

As you know in the WooCommerce itself you can not purchase a variable product and you should select one of its variations and there is same scenario here.

We checked the link that you have provided and the items didn’t have a default variation but it is possible to select a variation from a variable product.

I hope it helps.

Best Regards
