Around 50 pages having “feed” and “swcfpc=1” not indexed

I run my own wordpress powered website confidentpersonality.com . For past few days I have noticed that many around 50 pages are not indexed and they have swcfpc=1 and feed in their urls. Now someone please help whether it will negatively affect my website or not and signal Google that this website content is low quality further more provide a solution to solve this. I am using generate best theme and cloudfare DNS and cloudfare super cache plugin.
