Why didn't the warning system activate (two or four feed tanks, two or more separate alerts?), system failure, or was there something in the tank, what ...

Don't know what were the calculations based on, but according to th preliminary report press
conference statement, the PIC concludes that they would need to make as fuel efficient approach as possible.

On the fuel alarm, that is a misreporting. It did go off according to the FDR.
The mis-report may come from the wording. What is said in the press conference is that the alarm had NOT gone off by the time Bogota control handed over the flight to Medellín control (21 minutes before the crash), but that it did go off 2 minutes after that, so 19 mins before the crash.
