Accordion with multiple expand not collapsed

When I expand all the accordian items same time I won't able to collapse them again. What can be the issue? I have provided sample codebase.

<RadzenAccordion Multiple="true">
        <Items>
            <RadzenAccordionItem Selected="true" Text="Orders" Icon="account_balance_wallet">
                Details for Orders
            </RadzenAccordionItem>
            <RadzenAccordionItem Selected="true" Text="Employees" Icon="account_box">
                Details for Employees
            </RadzenAccordionItem>
            <RadzenAccordionItem Selected="true" Text="Customers" Icon="accessibility">
                Details for Customers
            </RadzenAccordionItem>
        </Items>
    </RadzenAccordion>

Use @bind-Selected instead

Therefore we have to define variables for each RadzenAccordionItem or is there any way to do that?
