MVCSiteMapProvider dries an invalid parent node id

I have this sitemap:

<mvcSiteMapNode title="Projects" controller="Projects" action="Index" key="Home" visibility="!*">
<mvcSiteMapNode title="Projects" controller="Projects" action="Index">
  <mvcSiteMapNode title="Project" controller="Projects" action="Details" preservedRouteParameters="id">
    <mvcSiteMapNode title="Session" controller="Sessions" action="Details" preservedRouteParameters="id">
      <mvcSiteMapNode title="Edit Session" controller="Sessions" action="Edit" preservedRouteParameters="id"/>
    </mvcSiteMapNode>
  </mvcSiteMapNode>
</mvcSiteMapNode>
<mvcSiteMapNode title="My Account" controller="Account" action="ChangePassword" />
<mvcSiteMapNode title="Admin" controller="Admin" action="Index" >
  <mvcSiteMapNode title="Create User" controller="Admin" action="AddUser" />
  <mvcSiteMapNode title="Manage Users" controller="Admin" action="Users" />
</mvcSiteMapNode>

When I go to the Session Details page, the breadcrumbs are displayed:

Projects > Project > Session

however, the project link that goes to the project details page uses the same identifier as the session, not the project from which it came.

I tried adding inheritedRouteParameters="id"Session Details to the page, but didn't change anything.

Edit: I added various saved RouteParameters, but now "Project" refers to / Projects / Details without an id attached.
