When in the ’presets’ screen using Sculpt Algorithm. Every time you select ‘back’ or ‘EQ curves’ in any view mode that displays the Algorithm column. The Algorithm column display will reset to the top of its list regardless of ‘By Type’, ‘By Use’, ‘By Name’, or ‘By Date’. All the other Algorithms that have two modes of control, preserve state of the Algorithm column, so this should be a bug.
Haven’t used my H9’s in a while, and just loaded 2.9.4 yesterday and found it right away.
