Issue with Predictive Search Add to Cart Button not working for first product result in Shopify Dawn Theme

I’m using Shopify Dawn theme.

In predictive search results, I want to add Quantity selector & Add to cart button beside the product listing.

For the first product result, tag is not showing, due to which I’m not able to add to cart the product. For rest product items, it works perfectly.

Store URL – https://demostore-theme.myshopify.com
Password – 123

Search with keyword – “de”

1st result – https://prnt.sc/vwKRqVRDTYS3
Console error – https://prnt.sc/M_8u_9O7Mm0e

For rest result – https://prnt.sc/DSWORL0h9FEY (works perfectly)

I have edited this code in predictive-search.liquid
