I have 2 columns merged in one like this:

```auto
            <RadzenDataGridColumn TItem="Employee" Title="Round 1" Filterable=false>
                <Columns>
                    <RadzenDataGridColumn TItem="Employee" Property="Score1" Title="Score" Groupable=false />
                    <RadzenDataGridColumn TItem="Employee" Property="ErrorCount1" Title="Errors" Groupable=false />
                </Columns>
            </RadzenDataGridColumn>

```

and this my UI:

Problem is when I group data:

As you can see, column headers have moved.

Is it correct behavior?

It works fine with the latests master branch. I hope you release this update soon.  
Thanks for reply.
