Please check the pattern on 60 and 40m where the 37m high vertical is going

You certainly will see the high angle lobes.

antenna is crescent shaped with its maximum at the midpoint, and a minimum

such lobes would seem to be the result of improper matching, or more likely,
the fact that in the real world such an antenna is in an environment that is
certainly not free space.
