Safari Mac - Print Labels

When I print a USPS/UPS, etc shipping label using Safari for Mac, label prints fine, but the Print Window reappears (prompting me to click “Print”. This only happens in Shopify. Not a huge problem but odd behavior and kind of annoying as I need to click cancel on window since it should have automatically closed after printing. Reminder, this behavior ONLY happens with Shopify. Works as it should on all other site, programs.
