It seems that sticky header don't work well on my webstie, but also on your demo page of Industrial theme.
If you click on the homepage - sticky header works. But if you go to other pages, and turn back to homepage, sometimes sticky header don't work. You can check on your demo page. I have the same problem on mine.
Can you please check this and solve the bug.

A huge thank you from BoldThemes in advance!
I cleared cache one hundred times in my browsers and in my site.. I tried to open your site in different PC-s and in different browser. Same problem again. Please check again your site. Scroll on homepage, then go to subpages, turn back to home page, again on subpages, turn back to homepage again....
Whether there is a possibility in code to fix the header?
Please note that the Sticky header functions properly on both - our and your website. The speed of its appearance depends on page loading since it appears after loading of HTML and CSS of the current page. If you are not satisfied with how it is predicted for the Sticky header to work, you can modify the header.misc.js file in wp-content/themes/industrial/framework/js/ folder.
Since the changing of the theme's functionality is out of the scope of our support, all changes you should do on your own. Thanks for understanding.
