Next Lesson and Previous Lesson not showing

Hi,

I am using a child theme for Divi and the next/previous lessons are not visible on the lesson page.

This is what I have done so far trying to resolve this:
Clear cache
Turn off all plugins
Active parent theme
Change theme to 2017 – it does work with this

So clearly the issue is divi, but I can’t figure out what the conflict is. I do have Liftilabs installed and configured as well. Its still not working. I also found the divi php in the support docs and added that code to the functions.php file and still nothing.

I just can’t figure out what the issue is and could use some help here.
