It might be, but I had rebooted more than once previously.  This time
I mounted them using the labels, so maybe *that* is the difference.  I
have another system running in VirtualBox from Linux (this one is not
a virtual machine) and I don't remember having any similar problems
with labels on it.  It doesn't make sense to me so I really don't
know.

I have checked many times and can't find anything different about that
FS compared with the others.  It isn't a misspelling because there
isn't anything in /dev/ufs except the other 4 labels that I am already
using.  There is nothing in the logs except the boot error in dmesg
when it couldn't find /usr to mount it.

The system works so I am not really worried about it.  It just
irritates me when I can't get things to work as I think they should.
