Unknown error when save in grid

[Soren M]

Hi - I am working on a grid to update data, and are facing an error, randomly appering. 

I get the error when editing cell's, sometimes first time, sometimes up to 15-20'th time I edit, in the same session. 

The log- 

   fail: Microsoft.AspNetCore.Components.Server.Circuits.CircuitHost[111]

      Unhandled exception in circuit 'Yy-4SjOaWwH6_4t7okdkIY2UEvvRx9sGtoBJgA2bByE'.

      System.NullReferenceException: Object reference not set to an instance of an object.

         at Syncfusion.Blazor.Grids.Internal.Selection`1.ClearCellSelection(Row`1 expect, Nullable`1 expectCellIndex, Boolean autofillSelect, MouseAndKeyArgs evt)

         at Syncfusion.Blazor.Grids.Internal.Selection`1.ClearSelection()

         at Microsoft.AspNetCore.Components.ComponentBase.CallStateHasChangedOnAsyncCompletion(Task task)
