This  is  a odd one when iam at  ftx  airport yscb after starting  engine 3   it  wont  allow me  to select  any  engine (start selector  switch) always  goes  back  to engine Number  3,   at  any other  airport its  fine  after  running  the afe  checks  i always  hear  him say  start engines  but  not  at yscb. Wonder  anyone  else  who has  ftx  yscb  has  the same  issue

This is also happening on my flights, seems like a bug to me. I have this on default FSX airports and addon airports. I have to switch off the AFE, he is snapping the switch back to 3. 

I let him do his checklist, switch him off, start the engines and after start I switch the AFE back on with "after start".
