Mermaid diagrams text has issues with greater than and less than symbols - it either ignores them or results in html tags. This occurs whether the symbol is encased inside double quotes or not.

Hi ​@Michael.Buttery, thank you for posting in the Lucid Community! I apologize for the delay in response here.

Would you mind providing me with a screenshot of the syntax and what results?

Are you receiving an error message that reads “Syntax error. Please check syntax” by chance? 

These items will help me to take a closer look!
