Hi Matt,

I tested this in 5.00pre10.

To maintain backward compatibility with previous versions (so the 
previous behavior is maintained) while adding the expected behavior 
that was not working, the submenu title should respect the following 
fallback rules:

1_ Submenu Title
2_ Menu Label
3_ Submenu Tagname
4_ Parent Menu

In 5.00pre10, fallback rules #2 and #3 are being skipped.

TIA,
Ady.
