Timeslips 2012 is changing the text I type

SOLVED

In my slip description if I type @u when I save the slip Timeslips is replacing it with Consultants.  This happens with quite a few other letters too, @a turns into Activities.  I have looked under Setup - Abbreviations and there are no abbreviations listed in either the database or personal tabs.  Do you have any ideas what is causing this.

Thanks
