Radzen Numeric use dot not comma separator

Hi!
I'm using a Radzen Numeric Component with double? as value. But the decimal separator is ',' not '.' . I don't succeed to change that.
Thanks!

My code :

<RadzenNumeric Min="-90" Max="90" ShowUpDown="false" Placeholder="Latitude" TValue="double?" @bind-Value="@coordX"></RadzenNumeric>

Thanks for your response. I tried it but i have this error :

System.Globalization.CultureNotFoundException : 'Only the invariant culture is supported in globalization-invariant mode'

This error isn't related to Radzen.Blazor components. Please search for it online.
