Issue Summary

The assignee filter should consist of the Assignee users of the tickets visible on the board but we see a lot of customers complaining that the Assignee users showing up are irrelevant.

Steps to Reproduce

1. Open Any Board (Scrum or Kanban).
2. Check for Assignee users filter and the list of tickets in the board.
3. You would find some irrelavant users in the filter. You can click on one of the Assignee users and you might not find relevant tickets.

Expected Results

Only valid Assigned users should show up in the assignee filters.

Actual Results

Shows Random users in the filter

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
