Extra code in slide notes translation tags when exporting to XML

Hi,

When I export to XML for translation, the slide notes get some formatting/font related code added in ({\rtf1\ansi\ansicpg1252\cocoartf1671\cocoasubrtf60 {\fonttbl\f0\fswiss\fcharset0 ArialMT;}

I assume this has something to do with font formatting in slide notes, as thhis never happened in older versions of Captivate. 

I tried removing all formatting from slide notes, but I still get the code inserted before the text that needs translating.   I imagine this will be confusing for the translators.

Any ideas on how to remove it so it doesn't appear in XML would be very much appreciated!

Thanks,

Kristina
