d_p_robinson: What build are you using? Did you have an earlier beta build installed at some point? If you delete the default C# autotext item for Encapsulate Field and then try the Refactoring can you please post the default C# autotext item that is automatically generated?
There was a bug in the way the default autotext items were loaded during install. This is fixed for the next build. In the meantime, just delete any default C# Refactor autotext items that you haven't modified. They will be restored properly when you actually use them.
