how do i get rid of the problems as shown in bold

Specify a BSP index for the command list "look_at_halo".

how to do that

When you select a command list in Guerilla or Sapien, you will see a "flags" section. In there, check "manual bsp index", and right under it, specify the bsp index in the text box for "manual bsp index".
