...
maybe you cancelled "first_update"
select the name with no hunters, then click config, then choose colour, then press ok (wait a few blocks.. like 5 )
if doesn't work, restart client
if doesn't work, restart client with -rescan
if doesn't work, it's that Chronos guy

we are looking into avoiding him
After hitting "config" and picking a color, my hunters showed up under my new entity after some number of turns that I'm unsure of.
