Master Tune Problem

After updating to V 0.26 I have found the following error with the Master Tune.
My tuning for all instruments is 432 Hz. I follow the procedure to tune the Super 6 but when I change the Preset, or leave manual mode it automatically defaults to 440 Hz.
If I press the “Shift” button sometimes it resets to that set at 432 Hz, other times it doesn’t.
Could you please check it? Or if I’m doing something wrong like not saving the Master Tune setting, I haven’t found in the user manual how to do it.

Thank you very much for your dedication
