Incorrect Shipping & Return info displayed in organic Google SERPs, how to fix?

An ecommerce site that I'm the developer for started getting shipping & return info displayed in organic Google SERPs, the problem is that it's incorrect. Right now it says "$25 delivery • 60-day returns" in grey text below the search result, but the company never charges shipping and has a 14-day return policy.

I have verified our that our product feed used for Google Shopping doesn't contain any shipping or return info, and the product pages themselves for structured data, and I can't figure out where Google is getting this incorrect info.

Where else might I look to correct this information with Google?
