Exporting ADM occasionally loses all movement infos?!

Hello.
I found Nuendo 13 will lose all the position info while exporting ADM file, sometimes.

  1. I have a project that can export ADM correctly.
  2. Remove one of the ADM input track, which has no any object movements.
  3. Playing the project, all other ADM track with object movements are played corrected.
  4. Export the ADM file for the current modified project.
  5. Create a New Empty Project and Import the ADM file above → all the movements are lost.
