Change language in Walmart Cart buttons

Hi there, I’m designing my online shop. Off course the Wolmart theme is setup in English. However I’m Dutch and almost everything is now changed in the Dutch language except for some buttons in the shopping section. In the shopping cart the buttons are in the wrong colors and English language, for example, Continue Shopping and clear cart. I have searched online and in the shop background, but I really can’t find it. I’m absolutely no pro so I really need help with this.
