Hx711 giving delayed/inaccurate readings

I'm working on a capstone project for high school and am using HX711 load cells. Basically, we are making a pair of scales. One is working as intended; however, the other is giving either extremely delayed or very, very inaccurate readings, and more often than not gives both. I have checked and compared the wiring and the code between the two and cannot find anything wrong. All I've been able to establish is that the code isn't the problem, and the solder probably isn't. I've only found one other person struggling with a delay problem, but from what I could tell the issue wasn't resolved.

Has this happened to anyone else, and have you been able to solve it?

(Video I used for reference, I followed its instructions for wiring 4 load cells together)

(Where I downloaded the library)

Thank you.

Check the continuity between E- on one side and ground on the other side of the board.
There are boards out there with a manufacturing fault, that don't have a ground plane on the back, so several parts of the HX711 chip are not connected to ground.

Will do, thanks.
