Difference between trash folder and deleted items folder in xfinity connect?

When i delete an email it goes to trash and not the deleted items folder. Why? ...

Messages placed in the Trash folder are later moved to Deleted Items to give you a "last chance" to save a message before it is permanently removed. For reference see https://www.xfinity.com/support/articles/set-email-deletion-settings. In addition, Email Expert @Latoque and Employee @XfinityGabrielS have posted:

• Spam is stored for 7 days or 5,000 messages, whichever comes first. Messages removed from Spam bypass the Trash folder and go directly to Deleted Items
• Trash is stored for 14 days or 5,000 messages, whichever comes first
• Messages removed from Trash are placed in Deleted Items where they are kept for 30 days or 15,000 messages, whichever comes first. These can be recovered (see https://connect.xfinity.com/appsuite/apps/faq/index.html#recoverEmail) and do not count against the 10GB mailbox limit
• Messages in the remaining folders are kept indefinitely
• If the 10GB mailbox limit is exceeded, new messages are not accepted
• Users cannot change these settings
