Thanks for the info. If this is after lines disconnected and reconnected it can be related to air in the system and reversed lines as I have seen this before. If no work was done then the problem can be in the control valve itself ( Inspect) or from a cylinder that has a problem internally such as a loose piston on the rod, etc. ( Pressure test in both directions. Let me know
