As you can see in this terrible gif: https://gyazo.com/199bb53de8b2be4920e4e3ce9094f1bd (if want a new gif that focuses more on the hatch let me know) there is no recipe going and yet the power going into the hatch is instantly depleted instead of being stored. Also know that I set the both ultimate energy hatches to store the max value of an int.

Blueprint: https://pastebin.com/eDiQv4zu (the multiblock is set to use any size hatch)

this is a gif of it being outside a multiblock: https://gyazo.com/4c66ad14c36cbc7e6a8d133d43f3f1db

Okay figured out the moment it gets to the max value it resets to 0.
