Importing a table and its index statistics, cannot import index stats

Question

Hi,
Oracle 10.2.0.4 on Solaris.
I have DBA to imprt tables and index statistics for a table from prod into QA for further analysis. The stats for this table are locked in prod
DBA has used the following command for export and import table statistics
exec dbms_stats.export_table_stats('SCHEMA','TABLE',null,'TABLE_20130225',null,true,'INV');
exec dbms_stats.import_table_stats('SCHEMA','TABLE',null,'TABLE_20130225',null,true,'SCHEMA');Although cascade is set to true above, this resulted in "only table stats" to be imported no index stats. So we have imported the prod table level stats but no index stats! FYI, the indexes in prod have stats (last_analyzed) set.
Next DBA tried the export and import using export_index_stats and import_index_stats but no luck. DBA advising me that the only option we have is to import the table itself from prod to QA. It seems that import with cascade does not work.
Is this a bug in 10g or there is another way around to get index statistics as well?
Thanks

"Gather statistics on the indexes for this table. Index statistics gathering is not parallelized. Using this option is equivalent to running the GATHER_INDEX_STATS Procedure on each of the table's indexes. Use the constant DBMS_STATS.AUTO_CASCADE to have Oracle determine whether index statistics to be collected or not. This is the default. The default value can be changed using theSET_PARAM Procedure."
