Text not displaying in PDF button

I created a custom PDF with a "reset form" and "print" buttons.  They were working correctly however after I reopened the file the buttons were still there and work correctly but the text is not displayed inside the button.  When I edit the page the "reset form" and "print" labels can be seen but when I preview the page the buttons are blank.    

I have tried:

Recreating the buttons

Changing text color, font, button color, outline color

Starting a new document

Changing the fonts

Repairing the adobe installation

I checked other threads and most of the problems were solved by making sure the button title was under the "name" and not "tooltip."  I have double checked that this is not the problem in this case. The pictures below show the way I created and titled the button Any help would be appreciated.
