Welcome to the forum!

The best way to work it out is looking in the editor. Find the group that is your Settings tab, and look under ‘Conditionals’. Is there a condition that’s causing it to display? If so, is it the condition you’re expecting?

I imagine that you need a condition on your Settings group:

When Get data from page URL is settings, this group is visible.

Inside ‘Get data’, you should have v, which is the URL parameter you. want to check. Now you’ve added a condition to show the element when v = settings, you can go to Layout and uncheck the ‘visible on page load’ checkbox, and check the ‘collapse when hidden’ checkbox to make sure it doesn’t take up any space when invisible.
