Remove [JOB & SECTION & LOCATION] dimension and add calculated dimension '=1'.
Now you should see flying balloon.
The problem with your data is that some sections have the same timestamp.
You could create keyframe_timestamp that slightly differs from that one but allows you to animate.
You can set =Color(FieldIndex('JOB & SECTION & LOCATION', [JOB & SECTION & LOCATION])) for X expression background color, to make the balloon to change the color depending on the section.
You can also remove animation, show arrows (presentation tab) and see static path image.
