All FURNACES OR RELATED ITEMS ARE ALL SET TO STACK TO 1

Looks like an issue with Furnace Upgrades then, technically it shouldn't let it stack by default if you set the stack sizes to 1. 

which means Furnace Upgrades should be removing / un-subing from the stack hooks?

he said it should be stackmodifer, you say it should be Furnaceupgrades.. we are going in circles here sorry to say

DId you set the furnace stack sizes to 1?

If you did mine should return false as well. Double check your setup 

I sure did sir

This says otherwise xD

If the stack size is 1 it would also return false, thus making this a none issue. 

according to /Stackmodifier

all furnace related items are set to stack size of 1

I assume the update resolves it ?

No, I have the same error.

I have tried to disable everything that FurnaceUpgrades uses, first I set it to 1 that didnt work ,then tried to disable it still same issue.
