Not all enemies jump off the ledge

hi, how do i make those enemies jump off the ledge i wanted to make those enemies fall like water fall off that ledge ':smiley: ,

i have tried the following:

  1. already added a bunch of nav link proxy
  2. tried changing collision settings
  3. tried changing the angle of the nav link proxy
  4. change the size of the capsul(nav link proxy).
  5. tried to check/uncheck the walk of ledge component

none worked, most of them still wont jump, and a few of them would jump but that is it, is there somthing im missing?
