This may or may not help. We had a Toyota 3 stage with the exact same problem. A real gremlin. We replaced the hydraulic line to the 2 stage cylinders and it solved the mystery. for some reason it was causing the cylinders to work out of sequence. This may be cheaper than resealing the cylinders. Hope this helps
