Configuration Keyword ArcSDE Personal

I've created a SQL Server Express geodatabase and was trying to import a feature class from the company enterprise geodatabase but the configuration keywords weren't available through the Feature Class to Feature Class (via import featureclass) tool. When I import into our enterprise db, I can specify a configuration keyword...so why can't I when importing to my sql server express database?

If I create a new empty featureclass in the express db (non import method), then I can choose a keyword. My configuration keywords show up in the database properties so I know they are there and visible.

Am I missing something?

Thanks,
