Wp Knowledgebase is effecting my urls (urgent)

I just posted my new blog and input the following correct url in Search Console to “fetch as google”: https://multiversecity.com/starving-artist-success-tips/

But, in the SERPS, the url shows this instead: https://multiversecity.com/?ajax=on&post_type=kbe_knowledgebase&s=

I deleted the plugin to see if that worked, but it still had that string at the end of my url.

Please help.
