Auto transformation is not working properly in jdeveloper 11.1.1.3

I was working with an XSL file in jdeveloper and i found the following behavior.

All the input fields are not mapped to all the output field in jdeveloper 11.1.1.3 when you use auto map feature.

That is when you select the parent node of source and map it to the parent node of target all the fields are not mapped ,some fields remains unmapped and has to be mapped manually.
