Any luck with this? A bit back mine also stopped saving to my pedal correctly.
I've been trying to search for a solution but am not finding one.
I've been trying to reproduce this problem, but so far I haven't been able to. Could you try resetting your H9s system settings to see if that helps? You do this by turning it off and then turning it on again with the right footswitch and the HotKnob switch pressed (the switch in the upper left hand corner of the H9). This will reset your H9s system settings but won't affect your presets. Please let me know if this doesn't help and I'll keep trying to reproduce the problem.
