I don't get that with WP 3.9.1 / 2014 / WC 2.1.8.
Your page also has 2 sets of social icons and 2 sets of page buttons. It looks like a corrupted page template. Please note we can't see your page markup or any customisations you have.
The general debug procedure is:
- deactivate all plugins except WooCommerce to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).
- resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.
- re-uploading all files & folders - except the wp-content folder and wp-config.php & root .htaccess files - from a fresh download of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones.
Take a backup before starting!
