AFCI Breaker Keeps Tripping Off

Why does my AFCI breaker keep tripping, is it because it is on a shared neutral wire?

AFCI Breaker Problem
[ad#block] Electrical Question: My AFCI breaker keeps tripping, is it because it is on a shared neutral wire?

I am remodeling a bedroom putting in tamper-resistant Outlets and arc fault breaker. The single pole breaker keeps tripping, I think because it is on a shared neutral wire. I have measured resistance between the neutral and ground on both the black and red wires I didn’t find a problem there. If I remove the red wire from a breaker then the arc fault works okay. Is it logical that the circuit with the black wire is okay and I move the single pole to the circuit with the red wire and it works okay that if I get a double pole arc fault it should work?
I just don’t want to buy it $200 breaker and find that it still tips.

This electrical wiring question came from Loren, a Handyman in Minnesota.
