[AMBER] the phosphoric acid group is deformed

Hi, amber users
    I am doing a simulation for a enzyme-ligand binding complex. The ligand contains a triphosphoric acid group. So I use antechamber to generate its parameters, and everything goes well. However, when I perform minimization and simulations, the end phosphoric acid group is deformed. In pymol, it seems that the three oxygen atoms bonded with each other. I do not know what is the problem, can anyone help me?
Thank you so much!
