Bug while editing Metadata

I tried to change the Cover image while playing a track. An error message appeared that write permissions were missing. When the title stopped playing I tried again. But in the window where you can change the cover image, the new cover is already displayed, which was obviously not accepted. If I select another image, this is now also no longer updated.

Can you please send some screenshot of what you are talking about?

I sent you a direct message with a screen capture video.
