The optional brackets accept multiple spaces between optional and main text (like between hello and (you|me) in 1st trigger). But if it happens that space is missing (likely an unnoticed typo), the matching for 2nd trigger will be how areyou and how areu, but NOT how are you.
+ hello (you|me)
- hi
+ how are(you|u)
- i am fine
