Internal error: Multiple tags with the same ID "Italic" have different start tag properties

Hello,

 

I'm working with Studio 2015 and I receive the same error message everytime Studio tries to automatically save my document. I received a package and opened it as usual. No update or plug in installed. My client works with Studio 2014.

How can I fix this quickly? Deadline is tight, as always...

 

Thanks for your quick response,

 

Ariane
