Import Export Wizard Column mappings

I am importing tables with a few columns of Varchar Datatype in DB2 . Inside SSIS 2012 Sql Import and Export Wizard converts all columns except a few correctly. There is a column of Type varchar(30) in Db2 but Import and Export Wizard is not able to recognize it . It used '22' in the Type column of MAPPING form . Please see the screen shot attached.

I tried to change the mapping file as suggested in other posts but still gets the same issue.

located inside C:\Program Files (x86)\Microsoft SQL Server\110\DTS\MappingFiles

I added

 <!-- VARCHAR -->
 <dtm:DataTypeMapping >
  <dtm:SourceDataType>
   <dtm:DataTypeName>22</dtm:DataTypeName>
  </dtm:SourceDataType>
  <dtm:DestinationDataType>
   <dtm:CharacterStringType>
    <dtm:DataTypeName>DT_STR</dtm:DataTypeName>
    <dtm:UseSourceLength/>
   </dtm:CharacterStringType>
  </dtm:DestinationDataType>
 </dtm:DataTypeMapping>

Tis still does not resolve issue. I have many tables to import and there are many varchar columns so manually changing all of them is a tedious. 

Any suggestion ? Thanks in advance.
