There is a typo in the message being displayed to a user when removing a coupon code. One 'l' when it should be two in 'cancelled'. `\vendor\magento\module-checkout\Controller\Cart\CouponPost.php` line 137 is currently: `$this->messageManager->addSuccess(__('You canceled the coupon code.'));` And should be: `$this->messageManager->addSuccess(__('You cancelled the coupon code.'));`
