yeoman generator not asking for application name

[DataBoyTX]

When I run the following: yo yfiles-app

and enter the options I want, it never asks for the application name and I get the following created in my current directory:

(base) [tcook@THOMAS-MacBook-Pro projects]$ tree -L 1 *
yFiles-for-HTML-Complete-2.3.0.3-Evaluation
├── lib
├── lib-dev
├── package.json
└── tools
yfiles-react-integration-basic
├── LICENSE
├── README.md
├── integration-howto.md
├── node_modules
├── package-lock.json
├── package.json
├── public
└── src

6 directories, 6 files

is this a bug or am I missing something ?

(base) [tcook@THOMAS-MacBook-Pro projects]$ npm list -g generator-yfiles-app
/usr/local/lib
└── generator-yfiles-app@4.0.1
