When I delete or move messages from some of my folders (Sent, Draft, and a few others), the message is not removed from that folder. The message is struck-through, but stays on the list. When I click on that struck-through message, it opens up.
When I delete or move messages from other folders (Inbox, etc.), the message is removed from that folder.
How do I get my deleted/moved messages removed from Sent, Draft, etc.?
