TAZ5 Cold Spot, never heats up, is this normal

In the image below I have marked around a spot that never heats up, it has been like this since day one. At first this hasn’t really be a problem but as my prints are getting larger its starting to get hard to rotate away from this spot. No matter the temp set to the bed, there is no heat applied in this section, around it I can’t touch it too long before I feel the heat, but on this spot I can hold my finger there as long as I want, just feels room temp.

That’s right where the wire interface is. There are no heating loops there. If you want that spot to be hot as well, your only option is swapping in an aluminum build plate.
