Product Specs are not loading up correctly

[AmericanFurn]

We had our products showing specs at one point but tailbase said it interfered with the product feed. 

Could any tell me a way to use this metafield, that tailbase provides us with to show our products specifications.

I have attached a picture of what we used to have.

and what it looks like now since they said that coding was affecting the product feed. 

for reference the theme is warehouse
