Linux editor splash screen does not show Unreal Editor

The title text for the editor's splash screen displays the text 'EDITOR' in a small font that is not bold.

I do not see this issue on Windows.

1. Download the editor from https://github.com/EpicGames/UnrealEngine/archive/4dca74afc70295d5249348712cfef2066abf8544.zip
2. Extract the files to any location
3. Open a terminal in the root UE4 folder
4. Enter './Setup.sh' into the terminal
5. Enter './GenerateProjectFiles' into the terminal
6. Enter 'make StandardSet' into the terminal
7. Open UE4Editor

The splash screen text to display 'UNREAL EDITOR' in a larger font that is bold.
