Error message in form Bad value: ‘designer_... only in Pro

Hi,

I get the following error message in my form.

Bad value: ‘designer_defaultHyphenation.para.hypenation’ of the ‘use’ attribute of ‘hyphenation’ element”. Default will be used instead.

The problem only occurs in Acrobat Pro not Reader. It seems as though Pro remembers things previously typed into the form field and then generates the error.

Perhaps there is a way to disable this feature? or?

Form created in Livecycle Designer ES2 V 9.0 Problem occurs in Acrobat X

Any help would be much appreciated.

Thanks,
