Thank you for your post.
This issue was originally reported in FileMaker Pro 10, and it looks like it was fixed in FileMaker Pro 11. Since this is now failing in FileMaker Pro 13, I have reopened the issue and attached your post to it. When I receive any feedback, I will let you know.
Thank you for the information and for reopening the issue!
I believe, however, the info about FM11 is incorrect: my tests show that FMPA 11.0v4 at least still has this problem (See Screenshot), and in my experience no version since corrects it.
