Front matter can't be changed?

[atomicbird]

Is it supposed to be possible to change the front matter? It seems no matter what I do, I can't get rid of

---
title: index
---

I looked at utils/file.js and I've tried to insert my own front matter but the default always appears. I thought I'd need something with similar formatting to the above, but adding that just means I get both my own front matter and the default.

Thank you for your attention.
I just started working at work.
In the evening, I will check the issue and answer it.
Thank you

Some more detail. I see in utils/file.js that the extractFrontMatter function looks for text at the beginning of a file that's delimited by --- at the beginning and the end. If that's not found for some reason, it throws an error and the front matter for a file named index.md is

---
title: index
---

But when I insert my own front matter I always get the default anyway. If my file starts with

---
title: stuff
---

Then the exported file starts with:

---
title: index
---
---
title: stuff
---

It seems like utils/file.js is checking for front matter but then always inserting default front matter anyway.
