Move_base: Why is the robot still using recovery behaviors if they are turned off?

edit

Hi all,

The current move_base launch file that I am using has the following parameters set as follows:

<param name="recovery_behavior_enabled" value="false"/>
<param name="clearing_rotation_allowed" value="false"/>

The wiki page for move_base http://wiki.ros.org/move_base states the following:

These recovery behaviors can be configured using the recovery_behaviors parameter, and disabled using the recovery_behavior_enabled parameter.

So why does the robot still perform clearing rotations if the related parameters are disabled?

Thanks
