yeah, it sucks. on the upper manual, right hand manual preset (Corresponds with B- far rightmost preset) - there's a 5th harmonic overtone getting through somehow when all the drawbars are turned off.
On the other manual preset (Bb) - it's fine.
On the lower manual (both setting) - it's fine.
Any ideas of how to fix or trouble shoot this issue. Just started in the past few weeks.
DANG IT

hammond A100 - drawbar stuck on (when turned off)
the new rules : there are no rules
Does switching percussion on/off have any influence?
Usually, percussion is triggered off the topmost (1') drawbar, which is the sixth harmonic, I guess. When percussion is switched on, that drawbar's harmonic is killed.
I've heard of mods that restore the harmonic even when percussion is on, or that route it to a different drawbar in order to enable the octave overtone - maybe something shorted there?

This usually indicates a partial short in that circuit.
Thankfully, these are built like ancient cars, where it is easy to trace a problem on an individual button or drawbar.
As analogika stated, try switching on / off the percussion section, and se if that influences at all.

That has all the service manuals, plus some experts on all things Hammond. I am sure if you are patient, you can fix it yourself.

Howling at the neighbors. Hoping they have more mic cables.
