I am working on a new unpublished version of our rental shop and I’m having trouble with connecting METAFIELD popup size chart to different vendors. I have already connected them to each product that it applies to but I am having trouble connecting the metafield option on the default product page. To be clearer, it looks like all my products show the size chart (STÆRÐARTAFLA) from one vendor only.

Here is a link to my product page:

Could l have listed it wrongly so it won’t connect?

The metafield connection doesn’t work on the product page default.

Thank you in advance.
