Keylab 49 Essential values changing in Analog lab

[SBedford]

Hi
Sometimes when I am playing with Analog Lab in Ableton, some values on the virtual synthesizer change on their own.

For example I was just playing with Prophet 5 - V and I noticed the sound had changed, I noticed that the VCA attack had changed in the Prophet.
I confirmed this by reloading the preset.

Has anyone else experienced drifting parameters or could suggest a fix?

thanks
