How to reproduce:

1. Open HUB;
2. Create 3D(HDRP) project;
3. Create visual effect graph in the "Project" window  (Create->Visual Effects-> Visual Effect Graph);
4. Drag it to the "Scene" window;
5. Select newly created graph in the "Project" window and go to "Inspector" window;
6. Click "Open" button;
7. In the opened graph window click "Blackboard" button;
8. Click "+", which is displayed in the "Blackboard" window.

Expected result: Menu opens and all the menu items should be displayed tidy. Menu items from two or more words should be displayed with spaces - human-readable format (users should see them correctly).
Actual result: Menu opens, but menu items from two or more words are displayed inconsistent: some with spaces, some not.
