Describe the bug
The left hand navigation appears to be busted in some places with Spring Boot showing up multiple times along with Testing Best Practices and Spring REST Docs

To Reproduce
Steps to reproduce the behavior:

1. Go to https://tanzu.vmware.com/developer/guides/graalvm-with-spring/
2. See error

Expected behavior
I expect to see Spring Boot as a top-level topic with Testing Best Practices, Spring REST Docs, Getting Started with GraalVM and Spring Native, and Spring for GraphQL Security... as sub topics under Spring Boot, only once in the left hand nav.

Fixed the part where Spring Boot shows up multiple times, but there are still cases where there are repeats happening - I think where there is a 3rd level. Still looking into this...
