Braids FM input

So it seems that I cannot zero out the influence of FM input. I am sending a sine wave from my Pittsburg Modular oscillator to the FM input on the Braids. Even with the FM depth knob at 12 noon I can hear some influence of on FM. It did not used to be that way. How can I fix it?

There’s a bit of tolerance on the notch width - moving it away and back to the central position can make it go away.

Seems like there is still some bleed. Especially when the operator is at a higher frequency. It can make the audio very sporadic or disappear. At lower frequencies I can get it to a state of being undetectable, most of the time, but still have problems when I increase the freq. This effect goes away completely when I disconnect the operator from the FM input.
