Maybe rf is leaking around the shielding somewhere?

Try replacing both antennas with dummy loads to
see if the harmonics are still loud. If they are,
try to improve in-shack shielding, such as double-
shielded coax.

How did you make the stubs? I haven't had much luck
using an antenna analyzer. I think a dip meter is
the best way. I think I would put the dip meter at
the antenna port of the stub box.
