Hi Steve.
there could be many reasons for this I will try to help:-)
1 the jack could indeed be too tall, maybe taken from an old upright or
something.

2: the jack could be glued to the whippen at a angle, or maybe not firmly
seated in the
 whippen.

3: The hammer butt could be the wrong type or a piece of felt is gone,
making the jack slip under the butt. does the hammer block?

4: somebody might have used a incorrect flange on the hammer butt.

5: the jack could be binding, some jacks are notched to clear the letofff
rail posts. every once in a while, someone will mix the jacks up.

6; weak or broken jack spring??

Thats all I can think of.
