Search not displaying custom field data

RT Version 3.6.4
An upgrade from 3.4

I have a search that looks at a custom field and adds it to the results
page.
This works 100% with a root account however normal users it does not.
My users Bob has all rights to the queue as well as the Custom Field
‘Simpsons’
Inside Custom Field ‘Simpsons’ is
Bart
Lisa
Homer
Maggie
Marge

I can search on just ‘Bart’ and it works great although when I add the
Custom Field ‘Simpsons’ to the ‘Display Colums’ the colum is blank.
The results of my searchs are below.

Search for Bob
