Problems with expression maps

When I open the MIDI editor and change its content by clicking various clips in the Project Editor - the MIDI content updates but expression maps don’t, i.e. the map stays unchanged per the settings of the track for first MIDI clip opened. So the expression map content in the MIDI editor doesn’t correspond to the Expression Map section in the Project Editor? As far as I can remember in N5.5 the expression map content was synchronized. Is there any hidden switch for that in N6?
