Groups.yaml is not updating/showing Overview

Hi all,

last weekend I have installed HA in the latest Version on Linux Ubuntu.

Since yesterday the overview is not showing what is written in my groups.yaml anymore. I can change whatever I want in my groups.yaml, it will not be dispalyed on the overview. I have already emptied my browser cache, without success.
Does somebody has a clue why? As I am a complete nobee, I don´t find a solution.

Here is my groups.yaml:

Ok, could fix it by my own. I just needed to add:

lovelace:
  mode: yaml

to my configuration.yaml.

Thanks,
