duplicated tags OG:IMAGE

WordPress 4.4.2 & 4.4.1

Hello,

We get the same issue in 2 websites located on 2 different hosts, both with your plug-in installed.

For the first (www.plentyplants.org), we get at least 3 duplication of the tag on the pages.
For example home:
<!– WordPress Facebook Open Graph protocol plugin (WPFBOGP v2.0.13) https://rynoweb.com/wordpress-plugins/ –>
<meta property=”fb:app_id” content=”926944744054235″/>
<meta property=”og:url” content=”https://plentyplants.org/new-little-monster-plants-b2c-website-part-of-an-omni-channel-experience-post/”/&gt;
<meta property=”og:title” content=”New “Little Monster Plants” B2C website, part of an omni channel experience”/>
<meta property=”og:site_name” content=”PlentyPlants”/>
<meta property=”og:description” content=”On littlemonsterplants.com kids and their parents can discover the amazing world of carnivorous plants. LMP shows kids that carnivorous plants are fun and interesting and to be treated and taken care of like real house pets. Doctor D. and his friends, Ula, Ned, Sara, Dro and Larry will tell kids all there is to know about these plants. These 6 Little Monsters Plants are already available in stores throughout Europe and with the new website kids can connect with them, have fun and learn at the same time! “/>

For the second online since only 2 days (www.littlemonsterplants.com), it’s the same, and number of duplicated tags change according to the different pages of the website:
<!– WordPress Facebook Open Graph protocol plugin (WPFBOGP v2.0.13) https://rynoweb.com/wordpress-plugins/ –>
<meta property=”fb:app_id” content=”1560275250968223″/>
<meta property=”og:url” content=”https://littlemonsterplants.com/”/&gt;
<meta property=”og:title” content=”Little Monster Plants?”/>
<meta property=”og:site_name” content=”Little Monster Plants?”/>
<meta property=”og:description” content=”Enter the world of Little Monster Plants?!
Doctor D. and his friends will teach you all there is to know about carnivorous plants…”/>
<meta property=”og:type” content=”website”/>
<meta property=”og:image” content=”https://littlemonsterplants.com/wp-content/uploads/2016/02/home-feature-2.jpg”/&gt;
<meta property=”og:image” content=”https://littlemonsterplants.com/wp-content/uploads/2016/03/home-feature-2-1024×510.jpg”/&gt;
<meta property=”og:locale” content=”en_gb”/>
<!– // end wpfbogp –>

Even by forcing the selection of right feature image in Facebook Debugger, the problem remains.
So it’s not always the real feature image who is called for sharing, but wrong one or blank one because referring to links from the OG tag who didn’t exist anymore
And as the OGP protocole is also used by LinkedIn and Twitter, it’s a big problem.

So here are my questions:
– how to fix and prevent the duplication of tags
– how to manually delete the wrong tags?

The problem is not only to stop generating duplicate tags, but also to clean the code with the duplicated tags.

Some idea?
