Default [Q] Callback Number Showing Up

So I just bought the G2 and have noticed that certain contacts now show their callback number when they text me. Both in the stock messaging app and Handcent. I was previously running Handcent on my Droid Bionic. Same JB 4.2.2 same carrier. Only difference is the Bionic was rooted. But, it had never shown cb numbers for other people before. I know people didn't randomly enable the cb optionovernight so that shouldn't be the problem either. Anyone else having this problem or know how to resolve it?
Thanks!
