Blog Feed Nav to next Page

The navigation at the bottom of my blog feed (to go to the next page) works until I go to page 3. https://www.2brokecooks.com/the-buffet-blog-feed/

I do not know what is happening, if a loop is getting stuck, but from page 3 onward, the link will change to https://www.3brokecooks.com/the-buffet-blog-feed/page/3/

It changes the “2” in my main link AND the page number.

I’m using oxygen theme, all up to date. Anyone else having issues or an idea on how to fix this weird loop?
