When moving from either Volume, Pitch, or Density tabs and clicking on Flam and adjusting Flam then this will also result in un-wanted adjustments in the aforementioned tabs/areas.
If coming from the Steps tab and clicking on Flam and adjusting Flam, all is good. No un-wanted changes.
*Edit, In version 4.0.2 and 4.0.3 - Wasn’t aware of it in previous version
