Imap sync issues

Been using Em client for a while now and all was fine, Only recently, when it syncs with my mail server (34sp) over Imap, it’s trying to download the entire mailbox every time. This is happening when we flip folders as well.  Any help?

I am having this issue too! Just started last few days after 2+ months with no issues. A restart of the program seems to fix it, but only temporarily.
