Thank you for reaching out to us.
Unfortunately, the “Contacts with Upcoming Birthdays” filter card is currently not operational and should be hidden from view.
The scenario was covered in our initial version 9 documentation as a known issue (see AFL-3320): https://documentation.nexj.com/crmdev96/welcome/release-notes/nexj-crm-release-notes/known-issues-and-workarounds/desktop
The wording is now outdated based on later versions of 9 and will be updated to reflect our current state. The general issue remains the same and a fix is currently targeted for the end of Q3 2021.
Presently, the existing workaround is to select the “Birthday” filter chip and use the “between” operator to select relevant date interval.
