I'm not for sure what verse you are referring to in Hebrews, but the fact that the early Christians in Jerusalem sold their possessions, and another group somewhere else "lost" their stuff is not a Contradiction.
It might be worth noting that Acts was written around 50-60 AD. Whereas Hebrews was written closer to 100Ad. If there is a verse that says what you say it does (I know of none), then it is most likely talking about a different set of Christians.
