Issues with editor mode

Help

Hello,
I am having trouble with my editor mode in Obsidian. It seems that headers, code blocks and pretty much everything do not work as it used to. The picture shows it better (I highlighted it) - you can see that previous notes look OK, but then something breaks.

What I’m trying to do

I want the headers and code block to work properly both in editor and non-editor mode.

It looks like you are using <ruby> tags to create the furigana. If a HTML tag isn’t closed properly, all markdown formatting after it will break.

I’d check in your Example callout to make sure all the tags are opened/closed properly.
