Website item "Select Variant" button does nothing in v14 (Develop)

The buttons do nothing. No server logs show up either when I click them. I have created a template, with 5 variants.

I’ve looked through all the settings and everything seems fine. I can publish the varients to the website directly but then they come up as separate items, which is not what I want.

Has anyone has success using variants, are there any tricks I am missing?
