RadTreeView not showing properly after migrating to 2010.

[Asset Manager]

 The telerik rad tree view is not behaving properly, we have it as a left navigation menu into a user control that gets loaded inside the master page. This issue is just  in some subsites of a big site collection migrated.

The menu will display the sites and subsites that SharePoint has.
The problem is that the arrows that it has on the left, ( see attached image please),  sometimes those arrows are pointing in a right direction ( right  for  the subsites of the site that im visiting ) , but in some other sites, the arrows wiill not show up correctly. This is all in the same site collection.

Here is the code. See atached image to know .

Is there any known issue about the styles or the misbehaving look & feel on the radtreeview on SharePoint 2010???

Help Please.

As I can see - you use custom css styles and images to display the expanded and collapsed states of the RadTreeNode.
There is an easier way to achieve the same.
Instead of implementing a complex client-side functionality to switch expand/collapse arrow you can simply override some of the build-in RadTreeView styles in this manner:

<style type="text/css">

div.RadTreeView  .rtMinus
{
    background-image: url("images/down.jpg");
    background-position: 0 0px;
}

div.RadTreeView  .rtPlus

{
    background-image: url("images/right.jpg");
    background-position: 0 0px;
}
</style>

<telerik:RadTreeView ID="CardinalRadTreeView" runat="server"
    Skin="" EnableTheming="false"
    SingleExpandPath="true" ShowLineImages="False" >
    <Nodes>
        <telerik:RadTreeNode runat="server" Text="Africa"
