Regarding the use of static path publishing in feature packs？

Dear Mr. Nasupl， In the function package, I found that there is a function package released by static path. According to my understanding, we need to draw the path first, publish the function package through the static path, publish the path to the robot, and then track the path through algorithms such as dwa right? Or can you guide me on the correct use of this feature pack?
I currently have the following problems with waypoints_nav:

When I was running waypoints_saver, I found that I can only store one calibrated point, which is the last position reached. This point is through the use of 2D_nav_goal in rviz
For the points marked by the button, did I have any problems during the operation? My operation method is as follows:

1、Start the sensor startup file of the robot (such as: handle, lidar, etc.)
2、Start the completed map
3、Start the waypoints_saver program
4、Use the handle to control the robot to reach a certain point on the map, and use the 2D_nav_goal button in rviz to mark the point.
When I enter the points into the waypoints.yaml file, but after starting the waypoints_nav file, the robot will not execute in the order of the entered points, but will automatically plan the path
I hope to get your reply, it is greatly appreciated！
