Web Application Branding in the new version 5.8

Hello all,

I updated my server to the new version 5.8 following this documentation: https://www.traccar.org/upgrading-traccar/
But I can't get the new attributes to brand the web app:
1-Logo Image
2-Server Name
3-Server Description
4-Color Primary
5-Secondary Primary

I check my server version and I find those value on: Setting > Preference > Info

App Version: 5.6
Server Version: 5.8
Conenction: Online

I have 2 questions please :
What App version refer too ?
Why I can't see the new attibutes added in this new version: ( I looked in Setting > Preference > Server > Attributes)

Thank you in advance for your help.
