Smetana Sonata for 2 players with 8 hands?

[Kammermusiker]

Hello, I noticed that the Smetana Sonata movement

https://imslp.org/wiki/Sonata_for_2_Pia ... %C5%99ich)

isn't listed as an original piece for 2 pianos/8hands although it is probably the most important composition in its genre. It is falsely flagged as a piece for two players, but the instrumentation however is listed correctly.

Fixed.
