Hi @SHECA-Alvin! This issue feels like a great opportunity where you could help contribute to ZLint. ZLint is a community project and as it stands, your request comes across as directly offloading the work needed onto other CAs and contributors rather than making a good faith effort to understand what happened. I would encourage you to investigate whether an existing lint should have caught this. If not, can you suggest a lint that would help catch this in the future?

Thank you for your reply. I will listen to your advice. Please allow me to do some research on zlint's code first. I am not very good at projects developed in golang language.
