Browser loading the wrong form

This happened once a while. Sometime when click an item in navigation menu, it does not load the correct form based on the navigation setup. Instead , it loads the form above the one that I click. If I refresh the browser, then it re-load the correct form. I have checked all the navigation slugs. Not sure how and why this happen?

I have ran into this issue before and I believe it’s a bug related to a visible_calc set on one of your menu items. Can you post your navigation schema?
