Missing keys in translation?

Hello,

I was trying to translate some stuff from CE 4.8.0 into Slovak language using the http://translate.oxidforge.org website, but it looks like there are missing some keys.

For example, in the file

/application/translations/sk/lang.php

missing keys:

PRODUCT_RATING
ORDER_SHIPPED_TO
SHIPMENT_TRACKING
YOUR_TEAM
etc...

Any ideas? Maybe I'm just missing something :)

Thanks.
