-with Waves plugins Insert Audio Effect / Recent; The plugins are listed but don't get added to he bin when selected.
 
-problems with duplicating audio tracks; automation envelopes/ nodes are duplicated however the parameters are not always assigned. Need to select & re-assign manually. Typically happens with fx automation & it's a random occurrence.
 
-Synth Rack; no issue but I prefer the greyed out box when synth is disconnected rather than the parenthesis indication.
