Driver's side seat, lower back support stuck??

I tried searching for this, but just came up with swapping out seats results.

My back support can only adjust forward and wont release or come back in. I tried taking off the plastic adjuster connected to the lever and the lumbar support adjuster, but I can’t see anything to fix/adjust on the outside of the fabric where its connected to what looks like a small gear.

It would be really great if anyone can help?, cause my seat sucks now. Ha!

Take the seat cover off, i did mine to fix the lumbar you just have to pull it up to see inside the seat you dont need to take it all off.
