Thank you for your post.
A new PDF engine was incorporated into FileMaker Pro 14.0.6 (and FileMaker Pro 15). Most new PDF issues are caused by fonts, but your issue appears to be spacing. If you go into Preview mode, is the spacing correct?
Reinstall FileMaker Pro 14.0.5 and see if the issue occurs.
I downgraded to FMPro 14.0.1 but is still happening.
I don´t see how it can be the spacing, if it was working before ande now is not, and i didn't change anything in the form...
If the issue wasn't originally happening, but now it is, something has changed. Send in a copy of your database file so I can determine what may be causing the issue. I have sent you a private message with instructions where to send the file.
