Thanks for your reply @swetakumari,
1] Do you mean change the title on the page and then update it?
Just update the page is not enough, but when I change the title then its good. But the point is that it would mean that I have to change it on 1000+ pages..
3] I want to remove all H1 titles, because it didn’t show up before the update and now all my TOC looks diffrent than before.
I know that I can eclude it on specific pages, but that would mean that I would have to do this on each page separately..
