Menu incomplete

Please have a look:
There are missing some items like Apps, Contacts in menu.
I was on 8.2 before, the menu was missing there already. I thought it will come back with update but it didn't.
Removed all folders in var/www/oncloud except data and config as it is described at some sites.After reinstall still no Apps menu. Also tried to change user in /var/www/owncloud/apps to www-data wich was root, but this did not change anything.
User is in admin group, as I see in database.
Added following to config.php:
'appstoreenabled' => true,
'appstoreurl' => 'https://api.owncloud.com/v1',

I think it is something simple. But after hours I have to ask here...
Anyone an idea how to fix?

User is in admin group, as I see in database.

Try to recheck this. An admin will also get the "admin" and "users" menu on the top right.

You were right. I was unable to add admin rights to exiting user. Don't know why it's not possible to change groups of exiting users with occ. So I created a new user with sudo -u www-data php occ user:add
--group="users" --group="db-admins" test. Then add my own user to admin group, where it was of course not.
Still curious how my admin rights get lost!

Thanks for this hint!
