Why is my add to cart button transparent when using dynamic checkout button?

I want to give background color to my add to cart button but it is transparent when I have dynamic checkout button enabled. Is it possible to give it color without disabling the dynamic checkout button?

https://pawnap.store/products/glow-stitch this is the url. I found out that in snippets/buy-buttons.liquid if you comment out this part

{% if show_dynamic_checkout %}button--secondary{% else %}button--primary{% endif %}

from this section

class="product-form__submit button button--full-width {% if show_dynamic_checkout %}button--secondary{% else %}button--primary{% endif %}"

it won’t make the button transparent anymore but there is no text showing on button if I do that.
