Might be a bug... check 4 updates...
I thing what I'm about 2 say is exactly what was explainned b4 but maybe it wasn't so clear...
b4 the step filter comes in write some automation that records you changing the type of filter used... so I guess when u reopen the session, even if it still resets, when passing this automation it should jump to the filter type u want!!
Let us know.. sorry if this was redundant!
