Thank you.

That second pipe is a lowercase L(hide cells at levels deeper than N). 
The issue also appears with 'c', but I don't think any others. Adding 
'a' (show all cell levels and all lines in cells) takes precedence over 
both of them, and will show all cell levels and lines no matter what 
else is in the view spec.
