Message Id of emails from IMAP is not the same as Gmail's message id

Hi, I'm working in deluge functions that get all emails of a module (zoho.crm.getRelatedRecords("Emails","Contacts",contact_id,1,200,{"type":5});), but the response message id of the email is not the same as Gmail's message id, Can you explain to me why it's different with each other in the same email.

In the same email but
