Media Encoder Queue Management Woes

I have some serious issues trying to manage the queue in Media Encoder (v26.3.1).  I loaded 250-odd items into the ME queue. After a couple has processed, I changed my mind and stopped processing the queue (red Stop Queue button). I then closed ME down for the day.

Next day, I restarted ME and I found that the Queue pane was empty with the status saying 2 of 252 items processed, a bad sign IMHO.  The Start Queue and Stop Queue buttons were greyed out. I dropped another file into the Queue pane and Start Queue turned green. I clicked Start Queue to start the conversion. ME then started processing the original queue contents from the previous night. Not what I wanted and a bit unexpected.

It seems I need to clear out the old queue. There must be a way to do this but I can't find it. I can't select the files and remove them individually as the old queue members are not visible since I restarted ME.

So, two questions:

1) How do I clear the ME queue?
2) How do I redisplay the queue members after restarting ME?

I would be grateful for any help...
