That’s strange, because the Headline Block inside the Container (Container is linked to #fortbildung) does not have the ID applied, as you can see on this screenshot.
However, I do see, that the Headline Block inside the Container still has the ID fortbildung applied to.
I have already recreated the Headline Block, but the effect is the same. It seems as if the Headline Block automatically inherits the target-ID from the Container wrapped around.
Then I have recreated the Container, which embeds the Headline Block, same result.
Then I have changed the anchor of the target block from fortbildung to fortbildung02, and also changed the link of the container, and now it’s working. However, when changing back, the same situation as before.
To me, it seems like a bug tbh.
In case you would like to check on your end, feel free to use the auto-login-link as provided in private note of my initial message.
Thank you in advance and kind regards,
