Closed Issue: Issue with 2.0 Beta: Get an non-Closing Element error [11085]

I have a situation where I have to open several XLSM files. Only about 50% of them work with the NPOI 2.0.
 
I get a failure similar to the following: The 'br' start tag on line 19 position 12 does not match the end tag of 'font'. Line 20, position 9.
 
The relevent stack trace is as follows:
 
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Xml.XmlException: The 'br' start tag on line 19 position 12 does not match the end tag of 'font'. Line 20, position 9.

I found that the EPPlus Excel library is able to read all the files without issue. I prefer NPOI but have to have a working solution by the next 2 weeks. Hope there is an easy fix for the Alpha release.
 
For proprietary reasons I cannot attach the XLSM file. Thanks!
