Yes the indicators turn off, and don't light up when selected again.
Using the filter for harmonics is responsible for the toned down harmonics when you choose the saw. The wave is selected for the pre made waves, but the button light don't stay on.
Also it seems like the "User" wave is not stored. The User wave is gone if you select another partial and then return. I can't see a way to store the User wave except than just selecting user. But it don't light up as it is now.
EDIT: Actually the user wave is stored if i edit the template sound "Sine". The user button don't light up.
And now it's also stored on another preset. Perhaps there is some preset specific in this. EDIT end
Also t's not possible to alter more than one partial at a time even following the multi partial select like described in the manual.
Hav'nt tried out that much yet. But this has to be fixed.
