[4.2.3] - app shows the content of other apps pages

I have 2 apps

Tools
ATP

Both of them has a page called home (home.ps1), both have URL /home -
the “root” apps has no code except something like:

New-UDApp -Title 'PowerShell Universal' -Pages @(
    Get-UDPage -Name 'home'
)

If I visit
/ATP/Home
I get a page not found

if I visit /ATP i get a page called “Home”, but with the the content of /Tools/Home…

No amount of renaming the pages changes this.
