When mapping an input element to an output element expressions are automatically generated to make the mapping work correctly. The automatic generation happens only if the expressions (that would be generated) were not previously specified. Though in most cases the automatically generated expressions will be what you want, this will not be true sometimes. In these cases you will need to manually alter them.
