As Junmei has explained, the problem lies in the fact that your starting
geometry is just bad enough that antechamber mis-assigns bonds. Junmei's
workaround does not appear to have worked for you, and I don't have any
practical suggestions other than: get a better starting structure.

This is not the correct syntax: type "help loadAmberPrep" at the LEaP prompt.

But that won't solve your structure problem....
