I have a website built with Bootstrap, and it works fine on desktop. However, when I open it on a mobile device(android + chrome), the hamburger menu shifts to the right after clicking it for the first time, causing the entire page to create horizontal scrolling and a band of whitespace below shifted hamburger menu. It is visible correctly when it loads for the first time. I am also attaching screengrabs and the url is https://www.globalmeds.in/

I cannot replicate it using developer tools on desktop. It works fine at every resolution in chrome desktop.
