Language Override for Next Button in Checkout

Hi, I want to change the "Next" button on the Checkout page to read "Proceed to Checkout". I created a language override entry for this. However it does not change in the display on the checkout page. I have one other language override preceding this one, which does work. Is the list comma or colon separated? Some other reason why the second language override does not work?

Thank you for the reply... on the check out page, currently there is a Next button and Continue Shopping button. I wish to change the Next button to be "Proceed to Checkout". I thought I could do this by overriding the "Next" value in the Language Override area. Attached is screenshot of the setting I changed. However the button still says "Next" and not the value that I assigned in the override.
