No Change visible, but themer shows custom theme set

[MaxOSchulte]

Hej,

i can't detect any visual changes after setting the theme in the config.php. Anyway the theme displays its message that a custom theme has been set.

Theming
You are already using a custom theme

folder structure

/ - themes    
  + themes / example
  + themes / material-dark 
  + themes / material-light

config.php

...
  'theme' => 'material-light',
...

Same for me, Nextcloud 11.0.5
BTW, example theme from the Nextcloud itself works
