Enable Image Replace stopped working

I use Enable Media Replace on a majority of my sites and I have them hosted through WP Engine. I just got off chat with them and they are not seeing errors on their servers. The images are not being replaced.

The correct image shows up when I use the URL the the ?time= parameter at the end (https://www.trindahealth.com/wp-content/uploads/2020/12/image-nurse.jpg?time=1606960941), but if you take that parameter off (https://www.trindahealth.com/wp-content/uploads/2020/12/image-nurse.jpg), my old image still shows.

How do I fix this?
