Hi Aaron,

Thanks for contacting us here.

For your information, this alert will appear when there is at least one variable product in a smart bundle or you have configured the min/max settings that requires to be met before buyers can add the bundle to the cart.

First, please help me check out this documentation to be sure you have created Smart bundles properly: WPC Product Bundles: https://doc.wpclever.net/woosb/.

Second, if you're using any Variations Swatches plugin on bundles, it won't work since our plugin cannot work with Variations Swatches plugins from other authors. You can kindly switch to this one https://wordpress.org/plugins/wpc-variation-swatches/ from our team to check if it works again.

Next, since your description lacks details, I would need more screenshots of your back-end settings and a link to your published front-end bundle for checking.

I'll guide you further upon receiving your feedback.

Best regards.
