Problem with RadzenDropDown adding Filter search

Hi, I gave a problem with RadzenDropDown filter, if i just use the filter for one radzendropdown it works but if I add this to another radzendropdown, there's a conflict.

My code is this:

If I add the filter in the Data @provinces it works and show all the values

<RadzenDropDown FilterCaseSensitivity="FilterCaseSensitivity.CaseInsensitive" FilterOperator="StringFilterOperator.StartsWith" AllowFiltering="true" Data="@provinces" AllowClear="true" style="width: 100%" Class="w-100" @bind-Value="@(searchLines.Provincia)" TextProperty="DescProvincia" ValueProperty="IdProvincia" Name="DescProvincia"

But if I do the same for the dropDown where Data @zoneRices i dosen't work shows a empty list and the list that must be there is showed instead in the other dropdown @provinces.

<RadzenDropDown FilterCaseSensitivity="FilterCaseSensitivity.CaseInsensitive" FilterOperator="StringFilterOperator.StartsWith" AllowFiltering="true" Data="@zoneRices" AllowClear="true" style="width: 100%" Class="w-100" @bind-Value="@(searchLines.CodiceSede)" TValue="String" Name="ZoneRice1">

Maybe there's an id or something?.
