Can't set rules on all tracks in slice rules list

Hi All,

I’m trying to use CB to quantize multi track drums. There are several good videos on youtube so I thought I knew what to do. But I’m having a problem.

All my drum tracks appear in the slice rules track list but only three of them allow me to set priorities. The rest are greyed out. I definitely made hitpoints in many tracks but still only three are available. It appears that only the first three are eligible to set priorities on.

Does anyone know how to set priorities for more than three tracks in the slice list?

All I had to do was click on the stars filed and the greyed out tracks became visible. Sorry for the silly post.
