Maybe there is an interpretation issue with colour coding and only the connected server shows green. Not in a position to make a quick screenshot, but secondary server shows grey as does your secondary server (Berta).
Edit:
The new functionality includes:
- highlight the servers in the list a
light shade of red or green depending on whether or not the server
responded successfully the last time it was queried,
- Highlight the last successful server in bold.
So it probably makes sense that the others are not green.
Another tip for those who struggle to get a green server, there is a restore to default option clicking on the 'pref icon on the top right on the Trusted servers screen. Typos are easily made after all.
