Reality Composer Pro "Create new scene in the project" doesn't work more than once

In Reality Composer Pro 2.0 (448.120.2), if I use the "Create new scene in the project" button more than once, this feature doesn't seem to work.

The second time I use "Create new scene in the project", Reality Composer Pro displays a new empty USDA file in the project browser with the wrong icon (a yellow document icon instead of a 3D box icon).

Also, it doesn't create the new scene's USDA file on disk or display the scene in entity hierarchy browser or create a new tab.

Consequently, whenever I want to add more than one new scene to my project, I have to repeatedly quit and restart Reality Composer Pro.

In my use of RCP just now, I had to quit and restart RCP six times to create seven new scenes.

Is this a known issue?

Repro steps:

1. In a Reality Composer Pro project, create a new folder using the "add folder" icon button in the project browser.
2. Inside the new folder, click the "Create new scene in the project" icon button.
3. Click the "Create new scene in the project" icon button a second time.

Expected behavior:

A new USDA file is created on disk. The new USDA file's root entity appears in the entity hierarchy browser and a corresponding new tab is created.

Observed behavior:

The USDA file for this scene is not created on disk and it does not appear in the entity hierarchy browser in a new tab. In the project browser view, a yellow document icon appears and it does not appear to correspond to an actual USDA file.

Thank you for any insight you can provide about this issue.
