Inconsistent JSON parsing through IOptions .NET Core

I'm building a Component that parse the appsettings that contains the sitemap and query to database to display the sidemenu.

I've bumped into a weird consistency error with the IOption pattern. It works fine on the first load but sometime the appsettings object is incomplete and my menu isn't rendered properly

I'm created a static class that fits my AppSettings. I registered it in the startup class. I don't think this is the issue since on first start the object is filled properly.

The component is called at each page load and rendered from the _Layout view

sitemap object successfully binded

After two page load, childrens are missing from one node

How is it possible that does value change ? The appsettings doesn't change at all

In case this is my model class

 public class SiteMap
{
    public List<SiteMapNode> Nodes { get; set; }
}
public class SiteMapNode
{
    public string ResourceName { get; set; }
    public string Href { get; set; }
    public string Icon { get; set; }
    public string Roles { get; set; }
    public int PrestationCount { get; set; }
    public List<SiteMapNode> Children { get; set; }
}

Here is the code that I think parse the appsettings on startup builder.Services.Configure<SiteMap>(builder.Configuration.GetSection("SiteMap"));

Here is a part of my appsettings
