Sidebar menu interaction reopening

Hello, I built a side bar menu but after cliking one link in the menu, I have to click twice on the burger icon instead of one for reopening the menu. After many tests I can’t see where is the mistake. Does anyone can see what’s wrong ?
Thank you very much for your help.
