"Reading" and "Want to Read"

Is it just me, or is it not working for you guys either? Also, I noticed that some of my ‘Already Read’ manga are being uploaded, but the ‘Reading’ and ‘Want to Read’ lists are still almost completely empty, even though I had over 400 entries there.

What do you think —will they be filled automatically with time or do we have to wait and redo everything from scratch?
