Terms panel with dash in field value displays incorrect values

[remmelt]

We have a host field in our logs. Each host has a dash: client-a1234, client-a2345, etc. The raw data and documents panel displays the field correctly. A terms panel does not, it currently displays:

host	number
client	10000 (what I assume are all log lines)
a1234	5000 (what I assume to be the correct number for this host)
a2345	5000

Is there a restriction on the field values?
