"Excessive Closing Force" and door groaning

Just installed a new Liftmaster smart garage opener and I noticed that the door makes groaning noises when it opens and closes, check it out:

Also, we noticed that once every eigth or ninth close, the open door retracks after traveling about two feet and remains open. The app complains that there's excessive closing force. I did adjust the torsion springs on my garage and noticed that when opening the garage by hand up to four feet it does slouch down around 2-4 inches. Does that mean it's unbalanced? I was thinking about completely redoing my torsion spings in the meantime; there's two of them and I'm assuming they should have the same level of tension, but let me get your thoughts.

Yes, the torsion springs should be evenly loaded. Some have a line painted on them which when tensioned form a spiral pattern to help you keep count.

I'm guessing to measure the distance of the spiral from the end points? Here's a photo of the them:

If I do a full release and retighten, how many rotations should they have?

Update:

So, I adjusted the springs. Before they slouched about 3-4 inches at the four-door mark, but now they retract about half inch. 10 or so test runs were all successful.

Not sure if I should just do a full reset of the springs at this point. Do you still recommend it?

Look at the painted stripe on your springs to see if each is wound the same number of turns.

I measures the white stripe from the side. It's 6.5 inches on the left, 8 inches on the right. Here's a photo:

I think it's the door. Something's going on with the panels. The motor and trolly sound fine as they're brand new.

Does it groan if you disconnect the trolley from the bar that pulls the door open?
Actually, it sounds pretty quiet to me. I can't hear any groans.

Post a picture of a center hinge they look unusual to me, also a picture of one of the rollers, the cheap rollers can cause the door to drag (not move smoothly)
