Check the hyd control valve lift&lower
Spool for adjustment and wear
If centering spring is weak or broken it can cause the spool to drop and let it lower
Also when you resealed the cyl I'm guessing
You replaced head seal and bottom seal
So that leaves hyd control valve or the
Velocity fuse
Velocity fuse is the valve that locks when lifted and holds the pressure on cyl rod
