This isn't _really_ a problem, it just doesn't seem quite right.
1- arm a session track for recording
2- prefs: record on scene launch is enabled
3- count in is enabled
4- start to record a clip into a slot, let the count-in begin
5- stop the transport before actual recording begins
6- remove the stop button of that slot, note that you can't now start a recording directly in that slot because the button is gone.
7- but start the scene, and it will still record a clip into that slot, until you hit the stop button for the track, or delete the clip which has recorded. Or disable recording on the track.
Essentially, it gets "stuck" with an invisible flashing record button in that slot.
I agree that a slot should stay record-enabled after transport stops even if nothing has been recorded. But it seems like removing the button from the slot should trump that.
