SCCM 2012 PC's will only pxe boot to task sequence set to "all unknown computers"

I have a strange problem, everything was working fine with sccm, i had created queries for each of my containers in AD, so i could set individual TS for each.

 

All of a sudden every single machine i pxe boot with will only pick up the TS if its applied to the all unknown collection. strange, like i said it was all working perfectly a couple of days ago

Ignore this, it was my fault, the machines in question were unknown, having one of those days
