I have the same thing happen. I have a community that works with parent volutneers and I often get the situation you describe in #1. Mr. Ms. Mrs. etc. or the club they belong to at their school etc.
I'd love ideas from others on this.
Josh that's a tough one. Because in an eternal community some people may not be inclined (or detail oriented?) enough to share that specific information. a couple things I've found that might help are changing it to "Job role" or "Job function" to try to eliminate confusion with the appellations (I think that's the right term for those). Depending what you really want to know, as an alternative or addition to text field input, you might also consider providing some sort of a drop-down of options of categories etc.
