Red syntax errors all of a sudden

[Davesakraken]

I've been working on a support site using mdx and have come to my project to find red text all over the files? This was never a problem before and all text was orange. Any ideas why this is happening? If I remove the top heading it seems to fix some of it but unsure why the headings would be effecting this.

The issue is a bug in VSCode's YAML parser, see the workarounds here: wooorm/markdown-tm-language#10 (comment)
