Problem with mouseDragged and multiple objects

We are playing with mouseDragged and multipleObjects.

We are trying to create a board game with 8 pieces that can be individually clicked and dragged to the appropriate location on the board (without using jpanel, jframe, etc.). So far we have created 8 separate pieces for the board game, however when you go to click / drag on piece "2" it makes all the pieces gather under the top.

Our initial solution (not shown) is to use a button to navigate between players, but we would like to try to do this without using the button. Any suggestions are greatly appreciated.
