Hello dergilb,
I looked at the savefile and, indeed, looks like you dismissed three SET at the very beginning of the game, and then you also dismissed another four in 1967.Q4. There's also an employee that resigned in 1967.Q3. That must have happened through a random event, though I cannot know for sure since I don't store that information inside the savefile itself. You can try digging up for the autosave associated to that season in order to confirm that the random event took place.
Regarding the stats in the end game screen... programmer error

I found out that I was printing the fields in the wrong order! It's fixed now, you'll see this in the next patch. Well spotted!
Cheers,
