How to select diagram type?

Hello. I use IntelliJ IDEA 135-1230 and MAC OSX 10.9.5.

I also use python and SQLAlchemy. I want to see SQLAlchemy diagram.

I checked SQLAlchemy Model Diagram feature and clicked diagram on context menu but there is UML Diagram only.

How I select diagram type? according to pycharm webhelp, there will be choice dialog. (see below)

I can't see this dialog ;(

I attach some screenshots.
