I have been to both profiles and changed Research Note to a third-level heading. The Research Note is supposed to go under the ==Biography== heading - but in this case, it's more like a warning! I can only think that your ==Research Note showed up strange because you need a == immediately after the words 'Research Note'.
I think putting it in bold is probably the only way of catching someone's eye! I have had to do it with my 9th great grandmother's name: she was called 'Philip', which was a local 17th century form of Philippa - but the number of times her name got changed or her gender got changed...
I think it's just a question of watching and changing it back if it happens again. Actually, thinking about it, since I put that BOLD note at the top of Philip's profile, it hasn't happened. Something else you could do is go into the Suggestions and mark it as a 'false error', because then it won't show up again on people's lists.
