Hybrid application

I am developing a brand new application in MAUI and have a problem with the entry field width. Whatever I tried I have following look of my entry field (too wide)


As you see my Konto field and Partner field.
Example code for Konto looks like this:

        <RadzenFormField Text="Konto" Required="true" Style="width: 100%">
            <RadzenStack Orientation="Orientation.Horizontal" AlignItems="AlignItems.Center" Gap="0.5rem" Style="width: 100%;">
                <RadzenTextBox @bind-Value="@model.Konto" Name="Konto" Immediate="true" Placeholder="7 cifara" Style="width: 100px" />
                <RadzenButton Icon="search" ButtonStyle="ButtonStyle.Secondary" Click="@OpenKontoLookup" title="Izbor konta" />
                @if (SelectedKontoNaziv is not null)
                {
                    <RadzenText Text="@SelectedKontoNaziv" TextStyle="TextStyle.Body1" Style="auto" />
                }
            </RadzenStack>
            <RadzenRequiredValidator Text="Konto je obavezan" Component="Konto" />
        </RadzenFormField>

What is the solution for this problem?

Found the problem. Stack and FormField are misplaced.
