No experiment slot on random kerbals

[Cavscout74]

After messing around a little with Breaking Ground in a new save, I decided to bring my 1.7 save over.  I copied & pasted the ROCSeed to enable the surface features as described in another thread here.  However, when I went to try to deploy some BG surface experiments, some of my kerbals are missing the slot in their action window to carry an experiment.  It appears random - spawning 4 kerbals in command seats on a rover, 2 had the slot & 2 didn't.  It isn't a permanent condition - Bill & Bob spawned several times in command seats without the slot, but then when they spawned in a Mk 2 lander can & EVA'd, they both had the slot. 

Has anyone else encountered this?

 

UPDATE:  I've now also encountered this on a new career that I started for Breaking Ground.  This time was also a command seat, so I'm thinking there may be a bug when spawning kerbals in command seats.
