You right it doesn't show up on dark mode (unless you highlight the text). Toggling dark mode off does indeed show it there!  Thank you for pointing that out to me, and at least we found an issue that has an overall impact on site visibility.  

I also never saw anything on the site while listing it that it applied an additional $10 for international shipping.  That may be another area to consider looking at while in dark mode.

It does not show that on the page, nor did I see anywhere in writing that an additional $10 was added for shipping on either the PayPal receipt, or the page indicating sale.  I have also been unable to locate where on the site it indicates buyers would be charged an additional charge for international shipping.  It is entirely possible I overlooked it however but would be great if that was indicated somewhere for the buyer to see as well.  Truthfully I forgot what I listed the item for as I listed multiple units, and had I realized it included an additional $10 in shipping I would not have arranged a refund to the seller.

It is not indicated on the PayPal invoice either and the page I can view looks like this:

Thank you.
