I have similar problem, I have FSUIPC4 and WIDEFS for P3Dv3 with name and only first family name but when I have purchased FSUIPC5 the name that Simmarket gave me is with first and second family names
I have sent them a ticket and this is their answer :
thank you for your order and we are sorry you are having an issue with any of the items ordered.
simMarket is only the commercial platform where the product is sold, however your problem seems to be specifically product related and/or of technical nature
Please contact the support addresses listed in the documentation for the respective product.
The support addresses are also listed in the respective product description pages in our shop.
If it is possible to solve the problem with versión FSUIPC 5.101, please tell me where to download it, because I d0n't find it at SimMarket
Thanks
