CS4 index code for subentry repeats...

I'm indexing a book and for each subentry I'm getting a repeat of the entry string concatenated with the subentry value. For example:



Agencies 357

Agenciesconsumer rights 359

Agenciesinterview questions 358

Agenciesregistry or staffing 357



Problem appears to be in Word Import where InDesign creates index codes with erroneous content. I've tested with with RTF, Word 97-2003 and Word 2007 format and the results are the same.



Running CS4 on Windows Vista. Index markers were imported from Word 2007 using Word 97-2003 format. Index worked correctly in Word.



I've got a 500 page book with complex layout that is ready to go once I get the index fixed!



Suggestions welcome, thank you.
