Any additional comments?

It was caused by canOmitUnusedDimensions.
when canOmitUnusedDimensions is true

1. prepareSeriesDataSchema only create necessary dimensions
   
2. DataStore is still generated with all dimensions.(see the length of _chunks)
   
3. SeriesData uses _nameDimIdx to reference the data in DataStore.
   Since unnecessrary dimensions are not created, _nameDimIdx is assigned the wrong idx
   
   
4. SeriesData._nameList is filled with wrong names
