plurals in rosetta

[Peter Chabada]

In some translations I found wrong plural expressions. Is there any way
to change it in Rosetta? I tried to download translation, correct it and
upload, but it is still wrong.

In Slovak is wrong:
n%10==1 && n%100!=11 ? 0 : n%10>=2 && n%10<=4 && (n%100<10 || n%
100>=20) ? 1 : 2

It should be something like:
(n==1) ? 1 : (n>=2 && n<=4) ? 2 : 0

How can I correct it?
