BaseAction with ITooltip

Hey,

We have a class that derived from BaseAction, and we wanted to be able to change it's tooltip text according to some conditions.

So we added the ITooltip to our class, and we successfully change the tooltip text.
BUT now it seems that there's a duplication of a tooltip object in the scene with the texts from our class.
In some cases(when we point with a controller on a button with tooltip), another tooltip is created in the center of the scene, and show the texts of our class tooltip...

What is the right way to change tooltip text or action icon for a BaseAction class?

 

Tried to pin point the problem, it seems that it's enough to implement the ITooltip for this to happen.
The tooltip in the center of the screen, appear when I select an object and pointing at it with one of the controllers.

Thanks
