Enabling translate of default language should not enable translation of the main language, rather parts that are differently marked, you can see on this site that it is enabled, and yet, you can probably not translate much on the default language.
Kuwezesha kutafsiri ya lugha default lazima kuwawezesha tafsiri ya lugha kuu, badala ya sehemu ambazo ni tofauti na alama, unaweza kuona kwenye tovuti hii kwamba ni kuwezeshwa, na bado, si pengine unaweza kutafsiri mengi juu ya lugha default.
