Hi,
I have the following allowed as Labels:
BUKGEN BUKCRA BUKHF BUKCA BUKCL BUKBB BUKCARDS
I want to create a Quick Filter to identify if anyone put something in the Labels field that is none of these (7).
The JQL's I created were this:
(1) labels NOT IN (‘BUKGEN’, ‘BUKCRA’, ‘BUKHF’, ‘BUKCA’, ‘BUKCL’, ‘BUKBB’, ‘BUKCARDS’) AND labels NOT EMPTY
(2) labels != BUKGEN OR labels != BUKCRA OR labels != BUKHF OR labels != BUKCA OR labels != BUKCL OR labels != BUKBB OR labels != BUKCARDS AND labels NOT EMPTY
But neither work ? Any suggestions very welcome ....... 
Ps they do filter out the missing cases (nulls) where labels is blank.
