Folder Display Order

I’ve used Thumbgen to create moviesheets for my TV shows. This has worked great but now when loading up my WDTV it displays the episidodes in alphabetical order rather than series order.
Have I done something REALLY wrong while composing the sheets?

I’ve everything labelled as:

Show Name - S01E01 - Episode name

The WD TV is sorting via episode name and displaying in an A-Z way

Theme im using is Mojo.

Did you figured this out?
