Selection of theme greyed out in profile

Hey there,

under my profile the option to select a theme / design is greyed out. It says Graphite E-Ink dark, however, I have already removed that theme in HACS.

In my configuration.yaml it says:

frontend:
themes: !include_dir_merge_named themes (two intendations are included)

There is no second "frontend" in my configuration.yaml

Do you have any further idea how to fix that issue?

Thanks in advance!

Kind regards.
