Bulk Variation - Quantity Typo in Box is Transparent

Hello,

After purchasing and setting up the Bulk Variations plugin, I have not been able to find a way for the quantity box to display the entered number of products that the customer wants to purchase.

When entering a quantity, the entered number is not displayed, but the product price is displayed and varies according to the quantity entered. It seems that the typography used for the quantity box is transparent, but it does recognize the quantities entered in the quantity box.

I am attaching the URL ( https://fullysickbrand.com/merch/ascolour-t-shirt-unisex-custom/ ) and an image of the problem.

I would appreciate your help in resolving this issue.

Thank you.
