Rainbow: table to XLIFF to table results in empty target column.

Created by: Anonymous

I use Rainbow 6.0.28 on Windows, with Java 1.8.0_60. Steps to reproduce:

1. Add input_example.txt to input list 1. This is a simple csv file, containing 4 columns, with single tabs as delimiters.
2. Set okf_table@custom.fprm as the filter configuration. This is an adaptation of the default csv filter, with columns 3 and 4 mapped to source and target, respectively.
3. Select Utilities > Translation Kit Creation.
4. Generate a Generic XLIFF package.
5. In the resulting XLIFF file, change some of the target text.
6. Add the manifest file to input list 1.
7. Select Utilities > Translation Kit Post-Processing.
8. Execute the pipeline.
9. Open the resulting translated file.
10. Notice that the 'target' column has disappeared completely.

If this is not a bug and I am simply doing something wrong, please let me know.
