Missing Folders - Sent and Unread

My eM Client program seems to be working correctly, just as it did before, but with one small exception.

In the folder list on the left, two folders have disapered - SENT and UNREAD.

How can I restore these two folders?

Thank you

Right-click on Favorites and choose Display > Unread and Display > Sent.

If Favorites are not visible in the sidebar, you can enable them in Menu > Settings > General.
