Styles of controls are not correct

Hi,
I am using Blazor server .net 6. The Radzen controls are working fine but the styles are incorrect(?). The picture is attached. Am I missing some setup steps? Why the styles are not matching to Radzen Demo controls? There is a double frame around the textbox if a value was changed. And the same problem with the date picker.
Thanks.

You have other global styles in your application except Radzen.Blazor component CSS.
