If you view the Logs report or the Statistics report, the breadcrumbs include the last two elements twice.

Replication steps:

1. Log in as admin
2. Navigate to Navigation > Site pages > Reports > Logs
3. Navigate to Navigation > Site pages > Reports > Statistics

Expected result: The breadcrumbs should include the last elements only once

Actual result: The breadcrumbs include duplicates

I suspect this is caused by the fact that these two pages appear in both the Navigation and Settings blocks, and in order to add them to both, the navigation has been affected and this has caused the duplication in the breadcrumbs.
