Some data formats don't allow that field names contain white spaces and / or certain special characters. In such a case, the writer replaces automatically invalid characters (e.g. white spaces) with valid characters (e.g. underscores).
Maybe your situation falls under such a case. You can use the AttributeRenamer transformer to change attribute names to appropriate names before writing. And you can copy attribute configuration from multiple Feature Types or Transformers separately. The writer will append attributes copied later to its attribute configuration, will not overwrite.
After copying, you can modify (add / delete / change) the attribute configuration manually on "User Attributes" tab of "Feature Type Properties" dialog box of the writer.
