Strings won't show up correctly in game

[fifty7var]

I've been having a problem where the strings used for localization aren't showing up correctly.

For example:

...
"HL2_357Handgun" ".357 MAGNUM"
"HL2_Pulse_Rifle" "OVERWATCH STANDARD ISSUE\n(PULSE-RIFLE)"
...

Shows up as #HL2_357Handgun on the HUD

Also, does anyone know how to get back the chapters in the New Game Dialog?
