Sync for gmail: copy messages from remote each time.

Each time i ran offlineimap, it would copy some messages from remote. But these messages were stored in a local dir. I am not sure why my offlineimap copy messages repeatly. I searched for a while, but don't solve it. Thank you for your help~. ( I followed archwiki for config.)
