ThingPredictor no parent row exists

Hi.

Today I'm trying to learn how the ThingPredictor works. I try the demo (Demo: Using ThingPredictor) with the JetEnginePredictiveModel and everything seems fine (I do the tut up to step 5).

Now I try it with my own models (and the vibration dataset from the Analytics Builder Quickstart​). In Analytics Builder I select the model and click on the publish button. After some seconds a new tab opens with the Analytics Manager and the opened Analytics Model. I do the step 4 of the Using ThingPredictor this model (including selected parant row (step 4.c.d.) with message "Successfully set Parent"). Add some values (step 4.c.f.) and the row and submit the job. Than I wait are short time. Click on refresh, select the "predictiveScore" in the Result Data Shape treeview and get this error message:

The same message appears when I click on importantFields. It look likes I haven't done step 4.c.d. but I do and I get the message "Successfully set Parent".
