How do I remove this 'ghost' of another master?

Hi,
All of a sudden another master is shown in gray while in editing mode (see attached image).
The condensed master is shown through all the other master.
Is it a bug or did I do it somehow? and how do I fix it?

Thanks
Daniel

Problem solved - I realized what I did. So just toggled off the eye icon for this master and it solved the problem :slight_smile:
