problems with 8GB cards and Genres


i have the Sansa 280v2 with an 8GB card and a 2GB card.

When I add from one Artist (easier to dupe) now one Album to the internal card another to the 8GB card, 

the player greates 2 same genres (example: Genre: TECHNO, INTERPRET: CASCADA, ALBUM 1 and ALBUM 2, now I copy Album 1 to the internal and Album 2 to the external card, results 2 same TECHNO Genres.)

This is not with the 2GB card, and I heard as well not with the 4GB card, only with the 8GB

Frimware is 3.01.16

Will it be solved with a higher firmware ?

Many thanks,
