Big clue as to the issue highlighted in bold. LEDs have much lower resistance, so, unless you have ballasts on them they read as "failed" to the monitor.

You mean infinite resistance of course because they're a diode and and will only pass current in one direction, in the other direction there is a forward voltage below which current cannot pass as well as an upper threshold above which the LED 'blows' and becomes a zener diode which won't glow any more.
