One temp fluctuates while others are constant???

I've been trying to figure this one out and I'm out of ideas. I have one temp probe that fluctuates up and down as much as 10 degrees and never sits still. The other two are constant and normal. What I've ruled out:
BCS is grounded to AC ground
All wires are running together for the sensors, so it's not interference from AC
I switched each probe with one another, so it's definitely something wrong with the probe itself, not the wiring from the control panel to the BCS
probe wire run is identical to one of the runs that has no issues
All coefficients are correct and the same
The only thing different about this probe is that I put a slight bend in it near the base to get the angle I wanted... but this shouldn't have caused this kind of problem... should it?
The only thing I could think of is that I got sent a bad thermistor? Or am I missing something here?
I tried to upload an image of the data log but it says the file type is invalid. Just try to imagine two flat lines and one wavy one that goes up and down with no real pattern or consistency.
