Hmm.. I'm not really sure why it doesn't work for you in this case.  I made an
EPD suite with those positions by copying-and-pasting and it worked fine on my
machine.  What happens if you put the third position first?  I tried copying
your setup exactly using the following in the "defaults" file:

hash 20
pawn 19
ponder
st 60
epdtest ccc
quit

The log file from this is as follows:
