how can i remove open graph meta tags?
The first set of Open Graph meta tags is probably added by your theme. You’ll want to remove the tags by editing your theme’s header.php or functions.php, where the theme author may have added the tags.
Another alternative would be to remove the second set of tags, added by Jetpack. You can do so by installing this plugin:

Do you have WordPress SEO installed?
WordPress SEO shouldn’t cause any issues, as Jetpack automatically disables its own Open Graph meta tags when WP SEO is active. If you still see 2 sets of Open Graph meta tags on your site, you’ll want to look for another plugin that may add these tags, or look through your theme files, or disable the tags in WP SEO by going to SEO > Social in your dashboard.
