Hi, 
I'm trying to figure out why some of my parent background are grey, and some are not.  In the page: 
https://help.smartsheet.com/articles/504734-hierarchy-indenting-outdenting-rows
about 1/2 way down, under "Expanding and collapsing.."
both "Administration" and "software engineers" parent rows are grey background.  
But in my sheet, only "administration" is.  "Software engineers" is not. My un-grey'ed parent rows are left-most indented.
Whats the difference?  How do I convert them?
screenshot attached
So in my case, "sanitation" "pest control" etc are not grey.  They are not related to the top-level grey "iso"
Thanks!
Jason
