Inbox won't keep up with webmail delete

I recently changed email providers and decided to go back to an email client to use with it. I had almost forgot these existed but they had some advantages over webmail. I am using it with AOL mail now.

I really like em client’s layout and ease of use, except for one issue. When I delete a message on the webmail for AOL, em client seems to keep that message in the inbox anyways. I am using the IMAP, not POP3, setup, and have the synchronization set for every 1 minute. What I can do to get Em client to remove emails from the inbox on the app when I have deleted them from the main AOL server or webmail? OE Classic does this right away, but there are some things I don’t like about OE classic as well.
