I certainly wouldn't purchase a font you've already paid for. The odds you'll get the exact same thing is nearly 100%.
My suspicion is the fonts are sharing an identical internal name (conflict). Neither the OS or any app then knows which is which.
If you don't mind, I could take a look at these and see what's going on with the font structures. Email a set to retoucher at jklstudios dot com.
You don't need to worry about me keeping a set for myself. Having been in prepress for over 40 years, I have at least 18,000 purchased fonts I almost never use for myself. They're all to have my own legal copies for working on client projects.
