One card, primary text and voice number set. Joe has two cell phones I text to. One is work, the other is personal. I have many employees that have the same issue. I can remember all the numbers, and I have texted them enough times that all Joe brings up now is history. Worse part is it's showing three history numbers for Joe. One is his home landline, which I have called but never texted. I'm thinking this is a bug.
P.s. Unless you have been texting someone with one card, and multiple cell numbers, I doubt you see this error, but I would expect you to at least see a history listing?
