Hyperparametertuning - Last attempt at Tuning question

Summary:

After we run the Demand Plan with Sample Size = 100, we realized that ~ 2,000 out of ~16,000 combinations have 01-01-2000 as the Last Attempt at Tuning

These combinations have all the other Hypertune measures populated like Bookings Forecast: Tuned, Bookings Forecast: Tuned Base MAPE, Bookings Forecast: Tuned Best MAPE but the Bookings Forecast: Tuned Settings are not populated for these combinations.

For all ~ 2,000, the Bookings Forecast has been generated on higher level. In our case the Bookings Forecast Level is either 3 or 4.

I did not see anything mentioned on the Help Center but can it be that the Tuned Settings are not recorded if the Tuned Forecast is not generated on lowest Level?
