I installed Product Label for Magento 2 in a custom theme (very popular named Codazon/Fastest_food_drink), however, in grid mode, there is a problem with CSS.
It opens a big gap between the image and the name price, please refer to the screenshots for your reference
The issue on the site is from the conflict between our module and the 3rd-party theme Codazon/Fastest.
The module is setting CSS 'position', 'relative' for the product-image-container so it breaks the CSS from the theme.
To fix this conflict, we would like to give you the hot-fix as below.
Step 1: Please edit this file
Step 2: Apply the fixed file and flush the cache.

We'd like to help.
