My EZ pages now all have the same title and heading.

I used page_2.php to create a Catalogue Request page. Then opened INCLUDES/LANGUAGES/ENGLISH/page_2.php and replaced define('NAVBAR_TITLE', 'Page 2'); & define('HEADING_TITLE', 'Page 2'); with define('NAVBAR_TITLE', 'Catalogue Request'); & ('HEADING_TITLE', 'Catalogue Request');.

I then noticed that my other EZ pages have Catalogue Request as the title and as a h1. I went back ito page_2.php and changed it back to the original 'Page 2' but the pages still have the Catalogue Request Title/Heading. I have no idea what i've done to cause this.

I've looked all over the forum for help but still none the wiser :( Can anyone please please help me........ i'm all zenned out !!

Hello all. I'm still trying to figure this out. I have also noticed it's affected other pages on the site, the main page, login and logout page and shopping cart pages. They all have "Catalogue Request" as the title and heading. It seems to be all pages apart from the product pages.
I have included a screen shot if that help. I'm using the current Zen Cart 1.3.8a version.
It's probably something really obvious but i just cant seem to work it out. Hope someone can help.
