[O] Intermixed date in koma-letter export

[York Zhao]

Let's say I have two letters:

  * Letter1
  ** Preamble :noexport:
  #+DATE: 2015-10-26 Monday
  ** To whom it may concern,

  * Letter2
  ** Preamble :noexport:
  #+DATE: 2015-12-03 Thursday
  ** Hi,

No matter whether I select letter1, or letter2, run `org-export-dispatch' and choose to export koma-letter, I always get the date intermixed in the export, i.e., "2015-10-26 Monday 2015-12-03 Thursday", instead of being "2015-10-26 Monday" when exporting letter1, and "2015-12-03 Thursday" when exporting letter2.

Please let me know if more information is needed.


Thanks,
