[Star Wars] Why do starships sink when they’re hit?

They immediately sink directly toward the planet, or elsewhere in space. Why??? They’re not ships sinking in the ocean.

Ships in star wars don't enter into a stable orbit when they're above planets, instead opting to use antigrav repulsorlifts to remain suspended in space. 

This however means that when repulsorlift system suffers a malfunction that gravity will pull the ship down like any other object.
