Sun automation trigger not working

I have an automation controlling my covers if I go to sleep or the sunset (30 min after) happens. It run for the last few month without problem. But since the latest update to 2021.9.x it stopped working. The automation does not trigger anymore for sunset, the sleepmode trigger still works correct only the sunset does not trigger anymore.

Here is the full automation maybe someone can tell me what is broken or if that is a bug. Automation has been created with ui edior in Lovelace.
