Issues with make null

Question

I have come across and issue with one our Ion consoles and was hoping you might be able to help. It would appear that all the patched channels have been made null and the normal methods of removing the null status don't work(ie. {make null} again, go to cue, sneak...) Do you have any suggestions on what to do about this? 
 
 Thank you

Sounds like you may have a Filter active. 
 If you locate the Filters softkey, and click Clear Filters (within the CIA) - this will clear any active filters and hopefully restore your channels to normal. 
 With a Filter active channels will look mostly Null except for one (or multiple) attributes. 
 
 Hope that solves it.
