I just created a new database in RM9. It only has two people in it.
I’ve added two facts to the second person and they are not sorting properly. The dates are formatted correctly, and their sort dates read correctly. RM recognized this as an error, but is not fixing it and I see no way to fix it.
FYI, while I am fairly new to 9 I have used 7 for a couple of years. I have two other databases in both versions and have never had a similar problem.
