Author Names Adding to END of Links? WordPress

I’m getting a ton of 404 errors on my site, its because for some reason every page has three versions of it somehow? The base URL, and then these two URLs below. One where it adds the author name capitalized, one where its lowercase, both of which are 404 errors.

I can’t figure out where this is happening. Its obviously not how I have my URLs set up.

Plugins I’m using are Yoast SEO Premium, WP Rocket, Imagify, Really Simple SSL, Ads.Txt plugin, and a few others.
