Do you think he will go to jail or OR'd?

My fiance is a registered sex offender from a few years back when he went pee behind a bar. Now he registered with our new address March 9th this year, but he was calling today to ask a question and they said he has an arrest warrant for failure to register, well when he called the original county it happened in they said in their system he is completely compliant, so he called the courts here back and they said he has to go in for an interview on Friday and see if he can get off on his own recognance or something, then he called metro here and the lady said I am so sorry this is happening and updated his info. but still said he has to go in on Friday for his interview, if he takes his paper in showing he is registered and when he registered and everything will this whole thing get cleared up?
