Hello TLW,
For the display, this current behavior is "by design". In fact it has been done to preserve oled screen. Don't worry, feature requests regarding this have already been logged in our database. Don't know what we'll be done , but for sure we'll think about it for next updates.
About the panel switch, let's give some explanation :
You press this button, preset sound changes accordingly to knobs (pots, not encoders, nor master volume) physical position. The panel button itself now behaves in a "gate" mode. this is exactly what is perceived as a bug , because on previous fw 1.0.5, it behaved in a "toggle" way.
Please consider that the only way to "exit" panel mode, is to load another preset.
I hope this is clearer for you now. But for sure, for a future update, let's consider this panel mode and other stuff (we've got LOTS of feature requests internally logged).
cheers,
