Hey Thorn-Sawskin,

One potential fix is to check if there are any conflicting settings or custom code in your theme that might be affecting how the testimonials are displayed. You might also try refreshing your cache or re-saving the section settings. If the problem persists, reaching out to the app support team or Shopify support might provide you with a more specific solution.
