Properties import needs to alligned as per mappings in the substitution mapping.  Also this implementation fixes couple of bugs mentioned below:

• Import Service, and see duplicated properties 'a::b::c::d' and 'a_b::c::d' (  )
• another problem: declare more that one input , select 2 properties and click 'Declare Input' - suggestion only for first one, and name of the second input is unchanged
