Sticky header is staying at the top of the screen when user scrolls back up.

Took over a site for a client and the old developers used “Industries” theme by Theme Kalia (not sure if that’s relevant or not) but the sticky header appears when you scroll down the page but when you go back to the top of the page, it stays at the top and covers the top menu and header.

The theme customization options are very limited and I can’t even find where to turn off the sticky header. We deactivated all plugins to see if there was an issue there (including the Accessibility plugin) and nothing except there is one called “Theme Support” that when deactivated, it completely removes everything but the header/menu’s from the page. When I go into that plugin, that’s where some theme settings are but nothing about a sticky header.

Any ideas?
