Crossover Analog LP and Linear-Phase options not splitting signal to multiout

[Aesaire]

Using MXXX6out with the analog crossover splits the signal into 3 bands and it comes out of 3 outputs [1,2] [3,4] and [5,6] in Reaper.

When changing the 3 band crossover to Analog LP and Linear-Phase mode only 1 output [1,2] produces a signal, which is a summed version of all three bands.

Is this a bug?

When MXXX6out has 1 band, it outputs each of the 6 lanes to a separate output. If there are multiple bands, it outputs each band into an individual output. Not obvious, I know
