Sadly that is a real world problem caused by the diode manufactures, I just ran into it with an LED. Normal Intensity LED: Anode-1 Cathode-2 High Intensity LED: Anode-2 Cathode-1 Ultra Intensity LED: Anode-1 Cathode-2 All three in the same package, marked the same way. :-( The pin out also can vary by color Red is Anode-1 and Green is Anode-2, :-( Bottom line is no mater what layout package is being used everything still needs manually checked...
