Application Upgrade Attribute List: truncated values

Hi All,

In Siebel Tools in view "Application Upgrade Attribute List" the values for columns "Prior Customized Value", "Prior Standard Value" and "New Standard Value" contain only values with 127 characters maximum.
The values are also truncated in the DB.

select max(len(OLD_CUST_VALUE)),max(len(OLD_STD_VALUE)), max(len(NEW_STD_VALUE)) from S_MERGE_LOG_ATTR

(No column name) (No column name) (No column name)
127 127 127

The Columns are defined with Text Length=500 in Siebel Tools and at the DB level too:

NEW_STD_VALUE (nvarchar(500), null)

OLD_CUST_VALUE (nvarchar(500), null)

OLD_STD_VALUE (nvarchar(500), null)
