You do not have a link list with a handle set to img-src-https-cdn-shopify-com-s-files-1-0037-1775-9045-files-2021-04-12_8-48-23_480x480-jpg-v-1618579790-alt-width-144-height-144, or you do and it's empty. Go ahead and create a link list called on your Navigation page and populate that link list with links that point to collections, to see collections listed here. Make sure the link list also has a handle set to img-src-https-cdn-shopify-com-s-files-1-0037-1775-9045-files-2021-04-12_8-48-23_480x480-jpg-v-1618579790-alt-width-144-height-144.
