Can't modify Widget BluePrint Variable

Hi All,

I am creating a simple menu, but I can’t change the values of my Widget Blueprint variables. I have dragged and dropped an Image under the Designer Tab. I set it’s anchors and size etc, then under the Graph Tab I select the corresponding Image Variable and try to modify it’s values. For example add a tooltip value. When I do it and save/recompile the tooltip text just dismisses…but this happens with any other option I try to set, as soon as I save/recompile it goes back to the state where it was.

Here is an image of what I am talking about:

Any help is much appreciated!
