Certain console commands/variables do not show their description text in the console window

Console variables such as "t.maxFPS", "CauseHitches", "t.unsteadFPS", and help "help" (these were all tested, there may be more untested with the same behavior) have description text in code however when calling these from the command line window the descriptions are not appearing in the window.

This is inconsistent with other commands (such as Stat FPS) that do show their description text.

1. Open UnrealEngine.cpp and go to line 6387 (4.10.2 engine - note the TEXT macro on this line)
2. Open editor with this engine (any project)
3. PIE and open the console
4. type "t.maxFPS" (no quotes) into command line

Result:
t.maxFPS appears in command window but TEXT description does not accompany variable name.
