Social ad insert does not work after saving page

I’m having trouble making this plugin work. I got it to work one time with a social ad inserted on a page. Then I tried to insert multiple social ads on one page, and it didn’t work … it only kept the first one. Then I tried inserting a social ad in a new page and it won’t work at all. When I insert the ad and save the page, the ad is gone.

Here is a video of what is happening;

Any suggestions?
