Moviesets not grouping correctly

Hi all,
I have read many posts about movie sets not working properly in the new skin but unsure if this is why I am getting the issue I see.

I use smart playlists for my movies so I can keep films seperate from live comedy and concerts and these are linked to from my home screen rather than using the movies option.

In the movies smart playlist I have the titles sorted by name and i see the movieset group followed by the individual movies...

i.e my library will be along the lines of

MOVIE COLLECTION - MOVIE 1 - MOVIE 2 - MOVIE 3 - NEXT MOVIE TITLE

Any help would be appreciated

:-)
