I edited my post because I was unaware of the second parameter (serverwide) of the function. In case you called it and it removed all the object, you may want to set the second parameter to 0.
I don't have samp installed so I can't test it to tell you for sure, sorry.
pawn Code:
Streamer_DestroyAllItems(STREAMER_TYPE_OBJECT, 0);
