Are those two pHats each connected to two different Pi’s?  
The pinout is here if that helps

Maybe its the Pi? Or a soldering issue? If its not to much trouble a good picture of the soldering might help.

Nice find @Crowbot. I’ve seen that mentioned on the Pi Foundation forum, forgot all about it until I saw your post.
