Mobile menu doesn’t work properly

Hello, I have a problem with mobile menu. The thing is that when I open the menu and click on Home it works fine, but when I click on About us or Services nothing happens, it doesn’t redirects. I already tried deactivating plugins and it seems that is not an issue. I use Colon theme. If someone could help me I would appreciate, thank you.
