Issues with rear adjuster

[l4d2mayhen]

Im kinda new here so i will be as detailed as possible.

So i replaced my brakes front and rear like 2 years ago, no issues with the front, the rear adjusters that came with the brake kit worked for a while then one of them doesn't move freely so i changed them both, few hours ago, rear adjusters turn backwards.The rear is a pain in the ass especially the auto adjusters. I keep losing rear brakes because the auto adjusters instead of expanding it contracts (the star wheel turns inside instead of turning outside), im not sure what causes it. It used to be both but i replaced both of them at the same time, same brand, left side automatically adjust, but right side starwheel still goes backwards. i need help because winter is coming and im exhausted with ideas on what causes this thing.

PS. I knew that i put them in the correct side and orientation, both of them has a stamp of L and R, and adjusters only go one way.

Any input is highly appreciated. Thanks
