Ionic lab platforms drop down missing

Ionic Framework ionic-v3
1

I created a new app using the standard start command:
ionic start dummy blank

when I switch to the folder and use:
ionic serve -l

There is no drop down for the platforms and no emulators display. All other apps created in the past work fine, any apps created now will not show the platforms drop down. Nothing has changed that I know of on my PC.

Ionic Lab is now a separate installation.

$ npm i -D -E @ionic/lab
3

It is installed, that is not the problem.
