From the param information you've provided it looks like you only have one observation source providing information for your obstacle layer while you have several sonar sensors on your robot:
obstacle_layer: observation_sources: laser_scan_sensor
A simple check might be to verify which sensors are located on the side on which you're getting obstacle data i.e. if it's the laser_scan_sensor.
