Newsletter page - missing text

[Guest larked]

If I login as a customer, go to My Account and look at the Newsletter page, it asks two questions, 1) subscribe to mailing list? and 2) in which format.

Strangly the text for the options in the first question is missing, i.e. the words 'yes' and 'no'. The buttons are there, just no text.

The second question is fine 'plain text' button and 'html' button.

I have looked in the relevant newsletter.tpl (below) but can't see what might be wrong (though I am a card-carrying-greenhorn so it may well be instantly obvious to you !)

Any ideas anyone?
