Issue Summary

Currently Custom Fields created through Connect Apps descriptor are not supported in the Two Dimensional Filter Statistics gadget. When configuring the gadget, the user won't see an option for such custom fields.

Similar custom fields created through the Jira UI, however, can be used.

Workaround

A possible workaround would be to copy the values from the Connect custom field into a Ui-created custom field using an automation rule. The user can then use the new UI Custom Field in the gadget.
