metafields in Athens Theme

Good day.

I have a problem with the metafields. I use the metafields to have a product filters. however, some of the metafields aren’t showing but still showing the products. I tried to raise a question in shopify advisor and they told me that they can’t fix this as this issue is within the theme. is there anyone can help me with regards to this issue?

I added the metafield through custom data and use the search and discovery for the filters. I export the product using matrixify to get the template and import it again in matrixify to fill those metafields

Since you’ve used Matrixify to import the metafields, make sure that the metafields are properly mapped and visible in your theme’s code.

Sometimes, the theme might not be set up to display all the metafields correctly. You may need to check your theme’s Liquid code to ensure it’s pulling and displaying the correct metafields.

can you help me to check in what should I need to find in the codes?
