I stumbled upon this problem and verified it on at least one demo on the telerik page:
If I create a two level grouping, collapse the inner group, then the outer group, when I expand the outer group, the inner group still looks like it is collapsed (it shows the collapsed image), but its contents is shown as if it was expanded.
When I click the expand/collapse (now in collapsed mode) icon to collapse the shown rows, the expand/collapse icon switches to the expanded image, and the rows remain in place. When I click again, it works as expected - the group collapses.
http://www.telerik.com/demos/aspnet/prometheus/Grid/Examples/GroupBy/GroupLoadModeClient/DefaultCS.aspx
has this behavior.
It looks like it's only a problem when using client-side expand/collapse.
