latest bug - MIDI not rendering in place & new saved fx chains not loading

so todays issue (new one every day it seems) is i cant render midi in place (audio still works) - right click midi part in the sequencer and the option to render in place isnt in the list. Further to this any new fx chains i save wont load in the inserts strip (old ones still load). any ideas how to fix. Have done the usual resarting etc. Cubase 9.5.30
