From the bottom of the Hero section, each Row ID is set, and each Row is menued and designated as custom link along with the menu text. When you click the navigation menu, you can go to that Row. There is no problem on the desktop screen. However, the problem is that when you check the mobile screen, if you press off canvas menu and click the desired menu, the screen location of the screen changes to the corresponding section, but the drop down off canvas menu screen does not disappear. When the first menu is pressed, the off canvas menu screen is closed while showing the corresponding section normally. However, from the second menu, the off canvas menu screen remains open without being closed. So, part of the screen of the corresponding section is covered. 

It was working fine until yesterday, but I've had this issue since today. Please help.

I always leave this part 'ON' but the result is same. 

And additionally, the form of movement from the second menu does not show the fast movement of the screen, but shows the corresponding section as the screen changes at once. Only the first menu also shows the normal movement of the screen. How can I solve this phenomenon? I think I need to save each row as a template and create a landing page again.

I'll try it and let you know if it's the same result. Please let me know if there's another way.
