– I restored system settings. No change.
– Then I noticed that all User presets were gone from Presets. (I checked a backup and found they were already missing before the restore.)
– Apparently, during "Save to iPad" any preset from the Preset List being saved will default to the generic "H91234 Presets" if it is not in Presets? (Except some missing preseits did save.)
– Now the question is, how did all of the user presets disappear from Presets?
