"All Mail" contains almost all emails (only excluding those marked as
spam and those marked as trash). Since you retrieve your emails once
via the "Inbox" label (which is essentially a view into "All Mail")
and once via "All Mail", you retrieve them twice.
In most cases it should be sufficient to just retrieve "All Mail",
since the emails will indicate in their headers how they were
labelled.
