If this is the first time that a certain email address has sent this type of bill to your Access Capture by Lightyear account, it will first appear in the Processing tab.
From the Processing tab you need to apply a map one time only. Once a map is applied, the subsequent bills will automatically appear in the Approval tab with all relevant data stripped out and coding applied.
If this is not the first time an email has been sent into Lightyear by this email address, check out the Statements Archive in case it has been accidentally mapped as a statement.
