Make: Electronics - Experiment 20

I finished the circuit which worked but I noticed 2 things seemed odd.

First, when I pressed buttons 1, 4, or 7 without pressing #, the LED attached to the # button would light. Is this the way the circuit should work

Next, when I entered the code out of sequence and pressed 7 as the 4th entry, the circuit activated. It seems that the latches on 1 and 4 activate no matter when these buttons are pressed and pressing 7 completes the circuit. Is this the way this circuit should operate?

Any help would be appreciated,

John Stark
