Can someone please check this form me (Minitaur)

I have come across a really weird issue with the Minitaur Editor 3.0.4 MAC (Firmware 2.1.1.). Whenever I save a preset of a setting in which I have tuned the second osc a fith above and then reload the preset, the minitaur does not produce any sound. Could someone check if they can reproduce the same problem? Thanks alot.
