"Toolbar" on the left of the screen that disappeared CATIA V5

Hello everyone, I made a wrong manipulation on catia and my toolbar on the left with the name of the room, all the sketches, plans, landmarks etc disappeared ... I tried everything: restore the contents, close Catia and restart the PC and nothing works. Does anyone have a solution? 

I'll put you a screenshot of my catia page in attachment.

Thank you in advance!!
