Dear valued customer,
I understand the issue you are describing and would like to provide some clarification.
Generally, the menu appears to be functioning properly. However, it seems that when the screen size is reduced, the scroll bar on the menu becomes visible. I assume that you would prefer the scroll bar not to be present on the menu.
Please let me know if this assumption is correct or if there are any other concerns you would like to address. I am looking forward to your response.
