value of send level lost in pt7 cs2

[m4tune]

Sometimes the value of several sends on aux tracks gets lost. With a stereo send also only one channel loses its value, which means that no audio passes to the output of this send(-channel).
This behaviour occurs only with sends which are routed directly to the analog outs of my 192i/o so far.
Perhaps only the sends H-J show this behaviour, but I´m not sure.
To activate the "accidently muted" send I have to change the according level only a little bit and audio passes again.
