Current Kill Team Rules in AB

[UndeadDan]

I'm just getting into 40K via Kill Team with some friends. I was trying out Army Builder and I cannot seem to make a valid Kill Team list. My stumbling block appears to be detachments.

I'm making a Tau team and all of the Detachments available call for things that are not valid with the Kill Team rules, like HQs and the like.

Can anyone walk me through how to go about doing this correctly? Or at least point out some likely sources for the error I am seeing?

Thanks in advance,

Dan
