Entity conversion in TW4winInternal Style in Studio 2015

Hi All,
I have a question about Trados Styles in Word in Studio 2015.

I have a file that I have marked up HTML entities using TW4WinInternal style and when Trados saves out the file it converts the entities to their "proper" equivalent.
So text like &lt;p&gt; that is marked in TW4WinInternal style is converted to <p>.

This was never an issue in the older versions of Trados that I recall.
I am using Trados Studio 2015 SR2 12.2.5195.7

Thanks in advance!
Bob Anderson
