The Aleena, who live on the planet's surface and have more opportunity to interact with the wider galaxy (note that they are relieved by the arrival of Republic supply ships but not surprised), do not speak galactic basic (English), but the Kindalo, who live underground and sequester themselves off from the outside world, do.
When R2-D2 and the two clone troopers enter the Aleena communication center to repair their mainframe station, the word "status" on the big screen is misspelled as "staus" in Aurebesh.
At numerous points, C-3P0 speaks galactic basic (English) to the Aleena, even though he knows they don't speak the language and he is fully capable of conversing in their native tongue.
