As title says: dispenser curretly dupping shears when you are trying to shear a sheep. You dont get wool, you get shears from dispenser (all shears that was in dispenser remains in it and lose durability) and sheep becomes sheared. So looks like you get shears from sheep instead of wool? Very strange bug. Tested on last version of 1.14.3 forge (27.0.24) w/o any mods - just forge. Works as intended on clear client without forge.
