@darwin-keem,
It looks like voxl-mapper failed to reach your goal point, resulting in it sending over the partial trajectory it solved for viewing but not giving you the option to follow the path. You can try giving the RRT solver another second or so by increasing the rrt_max_runtime_nanoseconds param, and it should be able to fully plan to your endpoint.
The path generation code has been rewritten and thoroughly optimized in the latest dev package, so if you are still having issues with this planner it may be worth checking out some of the updates on our dev repo.
