Cannot import custom rosmsg (actionlib)

edit

Hi,

I have very strange problem related to my custom action msg. I compiled my msg, but I can't import it. When I try to run my py action server I am getting next error:

raceback (most recent call last):
File "/home/ivan/infocom_robotics_ws/src/dock_station_goal/src/turn_for_specific_angle_server.py", line 5, in <module> from dock_station_goal.msg import DoTurnAction, DoTurnFeedback, DoTurnResult ImportError: No module named msg

But I can at the same time I can find my msg with: rosmsg list | grep DoTurn

ivan@ivan-desktop:~$ rosmsg list | grep DoTurn

dock_station_goal/DoTurnAction dock_station_goal/DoTurnActionFeedback dock_station_goal/DoTurnActionGoal dock_station_goal/DoTurnActionResult dock_station_goal/DoTurnFeedback dock_station_goal/DoTurnGoal dock_station_goal/DoTurnResult ivan@ivan-desktop:~$

Another strange thing is that when I am checking: rosmsg packages, the pkgs with my custom msgs are doubled:

ivan@ivan-desktop:~$ rosmsg packages

actionlib actionlib_msgs actionlib_tutorials base_local_planner beginner_tutorials beginner_tutorials bond control_msgs costmap_2d diagnostic_msgs dock_station_goal dock_station_goal dynamic_reconfigure geometry_msgs map_msgs move_base_msgs nav_msgs realsense2_camera robot_drive roscpp rosgraph_msgs rospy_tutorials rosserial_msgs sensor_msgs shape_msgs smach_msgs std_msgs stereo_msgs tf tf2_msgs trajectory_msgs turtle_actionlib turtlebot3_msgs turtlebot_msgs turtlesim visualization_msgs

You can see that beginner_tutorials and dock_station_goal are doubled

I am stack and getting crazy((( Can somebody help me?

Thank you!

EDIT

I am using catkin_make, the output of $ROS_PACKAGE_PATH is:
