PROBLEMS WITH DOOR HANDLE

Hi,
I´ve a problem with the outside door handles at the two rear doors of my H3. When I pull the door handle it stays at the pulled position and only goes back to the original position when I push it. This problem exists only at the rear doors. The driver´s door and the front passenger´s door don´t have this problem.
Does anyone of you have the same problem?
How could I maybe fix it?
Thanks,
Daniel
