Custom waveform not displayed correctly

Hi and thanks for this amazing soft synth.

I am testing the free version at the moment and I think I came across a little bug.

I drew a simple sine waveform on OSC1, saved it as wavetable and loaded the same waveform on OSC2. Now OSC2 still displays the init sawtooth. If I turn OSC2 off and on again (classic IT help desk suggestion, lol) then the correct waveform is displayed.

I am on macOS 10.14.6 / Mac Mini 2018
