Blazor server, select bar with nullable bool

I am creating the select bar for bool? type with three selections but if the null (third) button is clicked then the button is still not highlighted/selected. I've used the TValue="bool?" for this control but it has not helped.
The problem is with RadzenSelectBar Text="Not Set" Value="null"

Fixed and the fix will be part of our next update before the end of this week.
