Note the following behavior for when a Custom Upload Field > Select Field is added to the Upload form, and the Source is set as a Global Filter (as set under Admin > Filters):
- Any restrictions on Folders set under Admin > Filters will be ignored. The Folder Restriction applies to the Global Filter itself, not its values.
- Any restrictions on Divisions set under Admin > Filters will still apply.
- Whether the Global Filter is defined as Optional, or single/multiple under Admin > Filters will be ignored. The Custom Field settings will apply instead.
