Hi @David Filion
The Assignee dropdown list in Lucid Cards is populated by the names entered in the Assignee field of individual cards or tasks, rather than directly from your team list.
Currently, there isn't a built-in feature to edit or restrict the dropdown list to only your preferred team members.
If you notice unwanted names appearing, it's likely because they were previously assigned to existing or past cards. To remove these names, you'll need to delete or edit each card or task where they're assigned

Hope this helps - Happy to help further!!
Thank you very much and have a great one!
Warm regards
