Custom field advanced research problem

[Mike Donnarumma]

Hi, I recently installed Jira Service Desk and I've added some customer's emails to various organizations.

After that, I have a bad behavior an a pre-existent custom field in Jira called 'Resolver'.

'Resolver' custom field is a User Picker (single user) configured as :

User Filtering:

Filtering users by the following: Group: jira-users Edit User Filtering

Using basic research filtering by Resolver, the dialog shows only Jira-users BUT using ADVANCE RESEARCH tooltip shows all email addresses (even customer service desk emails.)

Could anyone have this strange behavior? It's probably a bug of advanced research?

Tnx in advance.
