Chances are that the internal comparator are disabled at POR.
i'd tested it here and's working as it's supose to. So i'll guess on a hardware problem. Maybe a way to high impedance on the A/D inputs, bad PSU filtering,... or worst... a short circuit between them 
Sorry it's working here.
BTW, you can even try to increase the ADC_SAMPLEUS value.. maybe.

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.
