Cannot add public library

Seems I cannot create a public library unless I’m logged in as an admin user? Is there a way to allow regular users to create a public library? The “add library” button is missing in the “shared with all” pane.

Seafile version 10.0.12, btw.

seahub_settings.py contains:

ENABLE_SHARE_TO_ALL_GROUPS = True
ENABLE_USER_CREATE_ORG_REPO = True

Any help appreciated… I’m probably overlooking something obvious. Thanks in advance!
