File Based Routing - Upgrading from 1.132.47 - 1.139.12

[harryevans1997]

I am a bit confused when upgrading @tanstack-router/react-router to the latest version. The generated routes have changed so that some index files no longer have a "/":

Here is an example of my file structure for the app index:

routes/ _app.index/ -components/ route.tsx 

This is causing the hooks such as useNavigate or useSearch implementations to be changed across my app as the routes have changed. I am using file based routing and haven't changed the file structure at all.

I am hoping for some guidance on why this might be happening and how to resolve it or a link to the PR that implemented this change as I can't seem to find it and want to understand if it's intended and how I need to update my app to accommodate the new changes
