Multiple Instances of Same Video

I am getting the following error:

We’ve detected duplicate video titles.
We’ve detected duplicate video titles in your sitemap or feed. Duplicate titles make it difficult for users to discern the content of the video. Make the titles more specific so they better reflect the content of the video.

Seems the plugin is creating multiple instances of the same post, but I can’t go in and delete. How can this be done?

Thanks!
