KB440430: 'Import prefix' is not working correctly in warehouse catalog in MicroStrategy 10.x

SYMPTOM
Sometimes, when users import prefix in warehouse catalog from Tool->Import Prefix, the prefix may be updated to the previous default prefix.
STEPS TO REPRODUCE

1. In warehouse catalog->options->view->table prefixes, define a default prefix.
2. Right click on a table used in the project->table prefix->choose a table prefix.
3. From Tools, click 'import prefix', the table prefix is changed to the old default prefix.

This issue cannot be steadily reproduced.
WORKAROUND
Please follow the knowledge base article to change table prefix instead of using 'import prefix'.
