Variables open in a new window

Somehow, I accidentally made all of my variables open in a new window instead of as a new tab next to script. How do I get them back in line with all the other tabs in the live editor?

Find this button at the top right of the variable window and click dock variables.

Hi, do you know why I can't open the variable window by doule clicking any variables?

Not only the variable window can't be opened, but also the 'ans' change to NaN.

P.S. Reinstall MAMTLAB can't resolve this problem !
