External Storage - AWS S3 - No folder

Nextcloud version (13.0.1):
Operating system and version (Ubuntu 16.04):
Apache or nginx version (nginx 1.13.10):
PHP version (7.2.3):

The issue you are facing:

When I configure an AWS S3 bucket as external storage, I don’t see any folder in the bucket that are created before in the bucket.

Via the nextcloud gui I’m able to create a folder.
But folders created via the AWS console in the S3 bucket are not displayed in the nextcloud gui.
