Buttons in PDF forms

I have added Reset, Print and Submit Form buttons to a PDF form.  I then go into properties and set the action for each button and save the form.  When I go back to recheck, the action has changed (ex.: Print a form has changed to Reset form).  The lower part of that screen hasn't changed, but I don't know if the top part affects the functionality.  What would be causing this to happen?  All the buttons are using the Mouse Up option ... could that be the problem?
