Chekmark Icon not showing

https://ibb.co/sgZQn9r
As you can see in the screenshots, the tick mark is not showing when the check-boxes. A red square box is shown instead, which is generally shown when the corresponding icon (in this case the tick mark) is not available. How can I solve this problem?
I’m using OceanWP theme and this is a woocommerce store
