Display MoreHa - problem solved! Kemper support had the solution - thanx to Burkhard!
A simple case of the pedal settings: morph > wah was activated. I wasn't aware that this setting also affected morphing via the morph button or via the slot buttons, but apparently this is the case: once I morph via the morph button or a rig button, the Kemper acts as if I had moved a morph pedal.
So as long as the setting morph > wah is on in the Pedals (or Pedal Links) menu, the Stage will react to morphing as if I had touched the wah pedal and temporarily activate the wah.
That's a funky one - nice to learn about the sophisticated pedal linking options this way!
Cheers,

The same here, great that I've found this topic! I've tried to find whats morphed, either in the rig manager or the stage itself (what has the M sign), but no cigar. Like fuzzmike said - it was driving me nuts! I thought that you can erase morph edits alltogether with the button, and thus i will set the clean plate and erase whatever was making the issue, but no... Finally, google-ing got me here, and voila! Thanks a lot!
