The translation of Slovak is somehow mixed, maybe because of import to Pootle. Even in Pootle it is wrong but I can't find a history where it comes from.
There are suggestions for translation in Pootle by me (rastorehak) and kleibl but they were never reviewed.
Examples from file Language_sk.properties:
javax.portlet.title.140=Site Redirector // Wrong, it should be translation of My Pages
javax.portlet.title.49=Site Redirector (Automatic Copy) // Correct, not translated yet
default-landing-page=Predvolený jazyk // Wrong
default-language=Predvolený jazyk // Correct
