Overriding Schema/Structured Data

I looked in my webmaster tools (Search Console) today and noticed that all of my article page content under the text is showing the Ad unit text (in this case Amazon). Every text block shows the SAME text.

I’m wondering if this is affecting my placing in Google SERPS?

Does this plugin filter into the Schema/Structured data field?
