4. Select any component, which title consist of several words
5. Click on preset icon
6. Verify, that "Select Preset" window opens
7. Find "Create New XXXXX Preset ..." line and create a new preset
8. In "Project" section find that preset and select it
9. Go to "Inspector" tab
10. Observe "Add to XXX default" button or "Remove from XXX default"

Expected result: Object names in all the buttons should be presented with spaces. For example "Add to Mesh Renderer default", "Remove from Mesh Renderer default", "Add to Box Collider default", "Remove from Box Collider default".

Actual result: Object names in all the buttons are displayed without the spaces. For example: "Add to MeshRenderer default", "Remove from MeshRenderer default", "Add to BoxCollider default", "Remove from BoxCollider default". Added screenshot in the "Attachments" section.
