You should share with us some more details!
Anyway, first thing that comes to mind: is "Unidirectional" property set to false?
Second, select "view as text", copy the two query properties definition in two notepad windows, and compare property by property...
Last, if you change the link grid-datasource-dataset, will it work the same? You will discover if it's a dataset (Query) problem or a grid one. If a grid one, compare grids properties as suggested for queries.
Hope this will help
