I assume it is the millionaire?

more likely that the plunger has a mushroomed end and is dragging on the coil sleeve, or some one has used a lubricant on the plunger and it is clagged up.
or even it could be getting caught on the End of stroke switch

Too much or too little clearance (up/down) bat to bush clearance when tightening the pawl creates sticking too, due to the angle the plunger has to return down the sleeve not being parallel. Line it up by eye and check it is going straight in

i was talking about the plunger that moves in and out of the centre of the coil.

9 times out of 10 on system 11 (9, 10, 11  ) if the flipper is staying up after the button is released it has got to do with worn or mushroomed flipper components or a magnetised coil stop on the flipper assembly

I would just replace both coil sleeves cheap as chips, easy
