coupon_admin.php contains double p tag

I am not sure in which version this started, but in Zen Cart 1.5.1 the language file coupon_admin.php (location: admin/includes/language/english/),contains two defines with a double <p> tag (line 51 and 52)

define('TEXT_COUPON_HELP_DATE', '<p><p>The coupon is valid between %s and %s</p></p>');
define('HTML_COUPON_HELP_DATE', '<p><p>The coupon is valid between %s and %s</p></p>');

This should be

define('TEXT_COUPON_HELP_DATE', '<p>The coupon is valid between %s and %s</p>');
define('HTML_COUPON_HELP_DATE', '<p>The coupon is valid between %s and %s</p>');

Found it in 1.5 - does it make any difference to remove or not?

You should remove it, it gives validation errors, and could cause unwanted behaviour/errors on the pages

In practice it's harmless. It won't break anything.

The duplication will be removed in a future version.

But if you're asking whether it's something you should lose sleep over, it's not. It's like the lowest level of urgency.
