You need to make your own channel selection from Adjust/Selection...  
because the channel names relate to the sources rather than sensor  
space channels.

This file cannot be really viewed in mne_analyze at all. The channels  
in the file are results of the inverse calculation and, therefore, you  
cannot expect to be able to apply the inverse operator to them again.

I hope this helps
