More likely a roller on the mast is digging into the rail! The cylinder is single acting, and is powered only on the up. To lower, the control valve just dumps the oil!. Is this single stage mast or a triple stage? Try using a spray lube on the rails, and look for any metal shavings, on either side , that would indicate a bad roller.

You say it hits a stop? See if the stop can be flipped over.
