I have the MTK module installed. The message keys found in that module are being applied to the dialogs of my custom module. I have a training light module (attached) with two dialogs. The page properties dialog is showing a help tip that comes from MTK. The textImage dialog has a form label being applied that I cannot seem to override.

The bug is that the name of the definition file does not seem to have any affect or create a distinction. MTK defines the property as basic.title.description. That should not impact the label pageProperties.title.description.
