LoadFromFile fails when opening excel book with many styles

[sonocibi]

Hello. I am a user of Spire.XLS Pro Edition Developer OEM Subscription.
Spire.XLS is embedded in my program. I provided my program to my customers.
When my program executed the method Workbook::LoadFromFile, Spire.XLS threw the "Duplicate style names has found" exception.
The problem occures when my program opens a particular excel book.
I extracted the excel book and found it had indeed a big style.xml.
I managed to fix the problem by cleaning up the style.xml manually, however, it's difficult to ask my customers to do the same way.
Do you have any work-around or any plan to fix the problem ?
For detailed information please see the atached style.zip(compressed) and Stacktrace & ExceptionMessage images.
Best regards.
