Dynamic Distribution Group stops sending email after updating filters

Ned help troubleshooting why when I modify my filters on my Dynamic Distribution Group

I need to add it to look add and have it look at CustomAttribute3 also. I tested it by removing the custom attribute 3 and group started sending emails ..   

here is my script

Set-DynamicDistributionGroup -Identity AllDetroitUsers -RecipientFilter {(RecipientType -eq 'UserMailbox') -And (CustomAttribute3 -eq 'includeAllDetroitUsers') -And (City -eq 'Detroit')}
