Does anyone know why I am unable to change headings on a confluence page?

[Chris Rowles]

New to this software, so still trying to understand everything, but today I came across an issue where I am unable to edit or change the font size to certain lines of text within the page I was working on. 

Trying to create an onboarding process with individual steps laid out inside the document. Everything works fine for the first 3 steps, about half of the full document length. I can change font size, and certain lines of text can be assigned as headings and so on. 

After this "third Step," I am unable to alter any font size or adjust the headings at all. Everything is in "standard size" font. Or, for lack of a better term, the second half of the document is locking me out from assigning the step names as headings. 

Has anyone experienced this, or am I just missing something? 

Thanks for your help!

Are you saying that you cannot apply any of the text styles available in the editor to the text—all of the paragraphs are using the Normal text style, and you cannot select a different style from the menu? As far as I know, this is the only way to change the size of text on the page.

Hey Barbara, thanks for the reply. That is correct; when I get about halfway down the page, the text style box you have highlighted in your image is not available for me. When I go to try and change it to a different heading, for example, the dropdown menu has a "🚫" overlaying it. 

I'm sure I can find a workaround, but just seems odd that it's doing this.
