WD Sync file structure limitation - all very odd

Having downloaded version 1.4.6698 I find that you are now only allowed to go down 1 level in the file structure when syncing. So what I mean is when setting up a sync, I can select any folder on my local machine, and the folder can be any number of levels down. But on the right hand side (the cloud) I can only go down 1 level. I thought I was going mad to start with, but to prove the point, I re-loaded 1.3.5949 and sure enough this restriction doesn’t exist.
So for me, rather than having to re-organise all my data I have had to roll back to 1.3.5949.
This is a very odd restriction to place on a new version !!
