Why does Custom Dialog fill whole screen?

When using FMP Advanced 14.0.4 and El Capitan OS 10.11.2., a SHOW CUSTOM DIALOG script step executes well but displays improperly. The message &  buttons look normal but fill an entire screen. The message is at the top left hand side while buttons are shown on lower right hand side. The buttons function as they should.

How do I shrink the whole page down to a normal size dialog box that pops-up in the foreground of the current window?

Is this a Filemaker or El Capitan issue?
