Name Generator not using/finding all names

Scrivener Rev
Select Writing Tools Name Generator
Select a bunch of possible names.
Select get male or either names
any obscurity level
what you get for a lot of them is either a missing middle name or a US for first or middle name

It all works just fine if you select only female names

See attached screen shot


I’ve tried this in Rev 3 and things appear to be working properly now.
