Within the top right of the list view for any project, it will show every single user within our site, including those that only have access to a service desk. is there a way to restrict this filter to only have access to the project? The users that show up do not have access to browse the project, nor are they assignable users.

What type of project is it, company managed or team managed? If it is a company managed project the assignee filter is based who have access to your instance, it is not just limited to who have access to the project.
