Unsolicited advice, but you have to escape your - to make it not create a bulleted list.

Lemmy uses markdown for its formatting, and this means - is has special meaning, it is syntax used to create bulleted lists with.

For example,

- Isaac Asimov will look like:

• Isaac Asimov

If you want it to look like

- Isaac Asimov

you have to escape the - character with a \:

\- Isaac Asimov

The \ basically says “ignore the special syntax meaning of - as starting a bulleted list, and instead treat it as a literal -”.
