Okay, further testing and it is possible this is related to Windows Creator update. I tested FMPA 14 also and you couldn't read anything in the dropdown - it was shorted, the opposite of what happened in FMPA 16. Then tried on another Windows 10 system that didn't yet have the Creator update and everything seems fine in both versions of FMPA.
Thank you for your post.
Our Development and Testing departments are aware of this issue under Windows 10 Creator. I have attached your post to the original report. When more information becomes available, I will post again.
