AMBER: Amber parameters for ADP

Dear amber-users
   Has anybody used the ADP parameters of Carlson (http://pharmacy.man.ac..uk/amber/)? I found that the topology of the molecule is not correct while viewing in xLeap. I don't know if this is relevant for the use of the parameter. Can anyone give some idea?

Here is the prep file.
