Why are rows missing from grid variables after merging data sources?
Merging data sources can result in missing rows in the grid variable. You can work around this issue by:
changing the order of InputDataSources.
adding the keyword namespace in the definition of question SI_Grid1 (and other questions using both ListSources3 and ListSourec8) in master document.
