Text Highlight not working on Trados 2015

Hi,

I'm developing a Verification Add-In for Trados 2014 & 2015.

The two add-ins are basically identical, besides the differences outlined in this article.

In the Add-In, in the ProcessParagraphUnit, I'm using the IBilingualContentMessageReporter.ReportMessage method to highlight the specific word that failed validation.

Strangely, in Trados 2014 the highlight works fine and the word is highlighted when I click the result in the results pane.

In Trados 2015, on the other side, it's not. When I click the result, the segment is marked (as in Trados 2014),

but the specific word is not highlighted.

Again, the code is identical.

What's the reason for this behavior?

Thanks!
