Category Problem - Bug?

Hi All,
I have a strange issue with the last 2 releases of the grpwise 2014 R2 client.
The problem doesn't exist in client versions 7, 8 ,2012 or 2014.

When an email is marked against a category the name and colour of the category is shown in the category column in older versions.
In 2014R2 only the colour is shown the text is missing from the category.

Has anyone else seen this problem and have a solution?
