The red line behind an IDCA fader is not correctly shown/updated in some cases.
Case 1: A linked channel's fader which is not shown in the same layer as the IDCA is moved. When I go the the layer with the IDCA, the red line still has the size from before moving the channel fader. It is only updated when I move the IDCA fader. (Only selecting the IDCA is not enough, it has to be moved for at least ±0.1 dB.)
Case 2: When entering any channel's or (I)DCA's menu, all IDCA red lines are removed and only restored for each IDCA after moving this IDCA's fader.
