LIMIT rotation Bone constraint issue

I’ve added multiple constraints to an armature bone such as CopyRot, LimitRot etc. But when I refer to the bone’s constraints with python via myObj.constraints, it seems that all the constraints are returned except for the “LIMIT rotation” constraint. When I print(myObj.constraints) all the constraints appear in the list EXCEPT for LIMIT rotation. Nor can I refer to the constraint in order to set any of its values. Is there an explanation for why only the LIMIT rotation constraint doesn’t seem to work with python? Or should I try reinstalling blender? Thanks
