Alerts cannot be displayed

Hi all,

we've just made a fresh new Hana instance on CAL, Update:68 (Apr 3, 2015, 1:40:26 PM), and when I open the Studio, it says

SQL error while updating the administration overview

Alerts cannot be displayed

and the error log has several entries

SAP DBTech JDBC: [2048]: column store error: search table error:  [29] attribute not defined for physical index;unknown sort attribute _SYS_STATISTICS:STATISTICS_ALERTSen/ALERT_TIMESTAMP

com.sap.db.jdbc.exceptions.JDBCDriverException: SAP DBTech JDBC: [2048]: column store error: search table error:  [29] attribute not defined for physical index;unknown sort attribute _SYS_STATISTICS:STATISTICS_ALERTSen/ALERT_TIMESTAMP

Is this a problem that can be fixed or is there some inherent problem in this instance?

Cheers,
