Outbound links changing to incorrect link

Hey all,
So on one of my pages, some of my links are getting changed automatically- and link to the wrong page.

This post was copy/pasted from my original site into this one, adn the links were broken from that point on. I went back in and removed all links and rewrote them, however it’s still messing up. I had set up a redirect, but since removed it because I thought this was the problem.
I did changed the publish date/time on this today, and I’m thinking that may be the problem, but if it isn’t, I don’t want to have ruined it more by changing it back.

Here is my issue: https://www.thriftycanadian.com/2014/12/new-baby-freebies-for-canadians/

If you scroll down to “Nursing Pillow” and clock on it, you will see it takes you to “https://www.thriftycanadian.com/2014/12/new-baby-freebies-for-canadians/www.nursingpillow.com” NOT just “www.nursingpillow.com” as I’ve asked it to. Funny thing is, the link above it works fine. Everything looks the same on the back end, so I don’t know what’s up.

Does anyone have any ideas?
