That's much clearer but I actually understood the first time. This is just bizarre. It is saying the temperature of the nozzles is reading just fine. There is seemingly nothing wrong with the heaters or the thermocouples. It is entirely in the Marlin firmware when if you ask for a temp it still displays 0 as the requested temp.
Seems like Marlin crashed or something. Maybe re-install it? Maybe get another Arduino. I don't know about Canada but in the USA they are about $20 including shipping. So why not buy two?

Better clarification now with a clearer head.
so i have an ulticontroller, if i plug in a heater cartrige in to heater 1 or heater 2 , then connect the thermacoupler amplifier and thermo coupler to the 1st or second input on the black cable.
on the ulticontroller it displays the current temp and the set temp.
if i set the nozzle of either 1 or 2 to a number higher than 000, it doesnt register the change on the lcd and the heather blocks do not change temperate.
