twebdbGrid incorectly selects everything

Hi,
When I left mouse click and select any two cells, the grid displays everything as selected.
When I inspect the elements I see that the wrapper tr class assigned to "selected" so this causes every cell including the empty area of the component show as selected color. And there is no way to exit from this state.
Thanks
