Well, I'm sorry to tell you this, but the Sodium Bromide indeed adds Bromide to the pool and the disinfecting chlorine (HOCl) in your pool will "reactivate" the bromide (Br-) to hydrobromous acid (HOBr) converting the disinfecting chlorine (HOCl) into chloride (Cl-). And unfortunately there isn't much you can do to get rid of it. It's not horrible having the bromide in your pool, it just means that you've got a secondary sanitizer that is less effective than chlorine and that whenever that sanitizer gets used, the chlorine will get used up to regenerate it. Not terrible, but not great either.

Perhaps someone else can tell you more and maybe find a way to get rid of the bromide/hypobromous acid or give you better news than I just did.
