Konquerer: Click on pinned panel opens in new panel?

So I click on the blue Konquerer pinned panel, but it opens a separate panel instance. Whats up with that?
How to open it in the main pinned panel button.

(excuse me for my language, not a native speaker and this is tricky to explain)

Is there maybe some other command to go straight to the filemanager? So I can make a pinned panel button where the filemanager opens in?

You can do it that way. You can see the house as an icon in the Konquerer above on the arrow then the window opens.
