Usage Report and Logging missing

Nextcloud version: 15.0.5
Operating system and version: Ubuntu 18.04.2 LTS
Apache or nginx version: Apache/2.4.29
PHP version: 7.2.15-1

The Usage Report and Logging sections are missing form my admin account’s settings page (see image). Disabling and re-enabling ‘Auditing / Logging’ doesn’t help. If it matters, my data resides on a different drive/directory but there are no issues with that (I migrated it following the directions).
