Issue ? - Ready API is not refactoring arrays in the rpc_literal binding to rpc_encoded binding

I have a request with set of array inputs in rpc_literal binding . I am trying to change this in to rpc_encoded binding using refactoring options. Once I refactored , input forms are not populating and when I looked the input request xml, namespace for rpc_literal still available for  the array elements .Which means, array elements are not refactored properly to rpc_encoded binding.
