Ionic 4: Issue Running Livereload with Environment Configuration Options

I seem to be having an issue using both the configuration flag and the livereload flag when running my Ionic 4 app on an emulator or device. I set my environments up according to the docs here: https://ionicframework.com/docs/cli/commands/cordova-run

and here:

https://ionicframework.com/docs/appflow/quickstart/environment

This cli command will correctly set the environment:

ionic cordova emulate android --configuration=qa

And this will correctly run with livereload:

ionic cordova emulate android --livereload

But when I attempt to combine the flags:

ionic cordova emulate android --livereload --configuration=qa

I get an error: Data path "" should NOT have additional properties(browserTarget).

Here's my ionic info if it helps, any insight would be appreciated:
