Sleep Shortcut

Hey guys, I had a short cut set up to put my computer to sleep (Option-Command-Eject). I set it up in System Preferences>Keyboard>Shortcuts>App Shortcuts then I added the short cut.

I then tied it to my keyboard (Logitech MX Keys for Mac) so that when I hit the lock button (F19) it would automatically do that hotkey sequence.

However the other day I found that the "Key Stroke" as Logitech calls it, got changed some how. So I deleted the hotkey combo so I could reset it without shutting down the computer... but my computer still shuts down and I now have no way to press those keys without it turning off.

Any ideas?

Thanks
