BBGHOSTS: in tree, but no host-info

Today I change the BBGHOSTS to a value of 0 (it was 1) in hobbitserver.cfg. After making that change I sarted seeing messages in my hobbitd.log for a few hosts that read as follows:
Hostname '%%' in tree, but no host-info

'bin/bb $BBDISP:$BBPORT "hobbitdboard host=%%"' returns nothing. I tried a 'bin/bb $BBDISP:$BBPORT "drop %%"' and it was no help. So what tree are these devices in and how do I get them out ? Hobbit 4.20 + allinone patch.

Thank you for you assistance,
