DDJ-FLX10 Stems mode on EQ

When I activate the part/stems mode on the EQ knobs and the settings are changed in the system settings to have vocals at the top, instrumental second and drums at the bottom... the artwork in rekordbox changes but the mapped knobs stay the say. Inst -Top, Vocal 2nd, Drums 3rd.

I would think it should map the knobs as is on rekordbox dj?
