strange sortation order

[LAZA]

I'm backing up my DVD collection and found the sortation order of Thunar - curious.

I had expected all films beginning with "A " to be listed first, BUT
A Walk Among the Tombstones (2014)
is the last, behind
As Good as It Gets (1997)

The Blank is traded as NOTHING ?

Cause the list goes:
Akira (1988)
A Knight's Tale (2001)
Alien -logy

THIS leaves me absolute speechless...
