The warning 763 "Prefix in Suffix" complains about Baronet appearing as a suffix, suggesting that it should be moved to the prefix.
Actually in English titles, this should always be a suffix (and is often abbreviated to Bt. or Bart.).
See https://en.wikipedia.org/wiki/Baronet.
John I guess the best thing to do is to read about the "error" Data Error 763: Prefix in Suffix you can also read then send them a message in G2G explaining what you believe here and use a couple of statements from your Wiki and wait for an answer you can then respond nicely of course and further explain your position. If it agreed then you can keep it there and leave the reason as a false.
They may have a reason it is that way or they may never have come across this before, Good luck.
