Hi JuiceKing,
Thank you for pointing this out. We were unaware of this issue. This is because the harmonic viewer is using a 200kHz span for each patch and at 100kHz center frequency, the previous harmonic is visible in each step. I can look into resolving this for a future update. A viable alternative for now would be to utilize the step entry, and use the arrow keys to step to each harmonic. I apologize for the inconvenience.
Regards,
A.J.
