Drop Down Box Font Colour Issue

Howdy,

On this site: https://masterantioxidant.ca/ if you:

1. add an item to the cart
2. go to the checkout page
3. select a province from the province dropdown box

The province selected does not appear, I believe the font colour is set to white once the province is selected.

I can't figure out the selector to make the text appear in this box. Please advise.

Support access is granted.

Thanks in advance.
Cheers,
Casper
