Playlists not appearing on Sony Home Theatres

I have a Sony BD-E380 and DBV-EF220 home theatres. Both are recognised with Sony 2012 profiles.
Media seems to be found correctly, but my playlists are not showing.
I have a mixture of Smart and Linked playlists and I have organised them under a top let set of playlists (for different member of the family).
Could this be why they don't show?

That will be the reason. In Mezzmo, left click on one of your playlists in the tree and drag it on top of the the Video, Music or Photo playlist in the tree (whatever is appropriate). That will move the playlist under the Video, Music or Photo playlist and now you should see it when you browse on your Sony device(s).
