ffTK employs a fairly simplistic algorithm to "autodetect" donors/acceptors. My suggestion is to:
1) use chemical intuition to assess which water orientation is most appropriate
2) you can use the charge data from the geometry optimization Gaussian LOG file to assess #1
3) go ahead and run the water interaction optimization calculations and look at the results to see which ones find reasonable energy minima
