STAAD foundation advances laterally loaded piles

Question

I am looking at using the cantilever pile design option, I am in Australia and realise the software will only design this type of footing to the US code. I would like to do the analysis, get the maximum moment in the pile then design the reinforcing by hand to the Australian Standards. I will still do a design to the US standard to get the solution almost correct. 
 Under "Soil Selection" there are 7 different clay soil descriptions and 7 different sandy soil descriptions. When selecting different soil descriptions I notice the "properties" don't change. Why are there 7 different soil descriptions, wouldn't you just have 1 clay soil and 1 sandy soil? 
 I have selected SI units, can I confirm the reo sizes are in mm? 
 Under moment/rotation I have selected "moment" as I have a free head pile. When I do the design and look at the calculations it tells me head condition "fixed head", why it should be "free head"? 
 I would attach my file but cannot work out how when posting to the forum.

Different options are provided for soil type as each soil type uses a different method for calculating the p-y curves. The soil properties are user inputs. If you need the software to calculate the Epsilon and J values, these should be left as 0. 
 When you choose SI units, the reinforcement bar sizes should be in mm but I came across one section of the input ( Design Parameter > Reinforcement ) where the bar sizes, reinforcement strength, Modulus of Elasticity all seemed to be considered in English units although SI units are chosen. I have to refer this to our development desk for review but for now I would suggest that you use English units only. 
 Yes if you select the Moment as input, the Pile should be considered as Free Head. The calculation sheet however reports the head condition as Fixed Head and I think this is a reporting error that we need to fix.
