It's almost certainly a cosmetic issue in Hawk.  I have fixed one or two 
bugs along these lines since version 0.3.6.  If you'd like to try a 
newer (not-officially-supported-by-SUSE-but-best-effort-support-by-me) 
build, you can try hawk-0.4.1 from:

http://software.opensuse.org/search?q=Hawk&baseproject=SUSE%3ASLE-11%3ASP1&lang=en

Alternately, if you can reproduce the issue then send me the output of 
"cibadmin -Q" (offlist is fine), I can verify/fix it.
