Check boxes for forms and opt ins dont show the tick

Hi there is a problem with check boxes, e.g. when you accept ts and cs or when you want to select shipping address etc. in woocommerce.

please see image attached. the boxes are clear and you cannot see the tick when you check them and also, they are formatted weirdly

This problem also leads to an issue with people trying to purchase our products and then not knowing if they need to enter a shipping address or not. And sometimes they enter a shipping address but because you dont see if that is ticked or unticked, the system does not identify a shipping address and gives a shipping address error when they try to purchase.
