Scripting Wavelet Compression followed by derivatives filtering leads to dataset with too few columns (Q821)

The information in this article applies to: 
SIMCA 14
Symptoms: 

When filtering using scripting and first using Wavelet Compression and then either Derivatives or Savitzky-Golay, the resulting dataset incorrectly lacks several columns.

Workaround: 

In the script, complete the first filtering and use the resulting filtered dataset as input to the second filter.

Status: 

Will be fixed in the next release.

More Information: 

This is only incorrect in the scripting part. Using the regular user interface this chained filter results in a correct dataset.
