Link menu sheet

I add a menu wich was based on a sheet. I have deleted some rows in my sheet and now the link is not good.
I can’t change it, have you an idea ?

My Spreadsheet’s tabs :

My menu :

The option “Réservations à valider” should be link to “Réservations” sheet. I can’t do anything.

I already have a menu on “Mon compte” :

Look this video, i can’do anything with both menus, when i want to move one, the other move…

Have you tried it in a different browser? Try clearing the browser’s cache.

I solved the problem by deleting the “My Account” sheet and creating it again
