This should not be a bug, and it is natural behavior how the appsheet views are presented on Dashboard.
When you see the table view with grouping, then hit one selected group, it will keep drilling down, but not put the name of selected group after dumping to the subsequent table view.
However, once the same table is placed on the dashboard, selected 1st grouping items is pinned on the top of the rows.
On the dashboard view, hitting the first row (selected group name) is bringing us back to the previous table view which is showing grouping. Without this, we are not able to come back to the previous view once the group is selected.
