Problem with Showing Data on UMG!

Hallo I am having some trouble with Showing Variables or in general data on an UMG. So I have created a Pawn where I have set up an Event Dispatcher to Update the UI. In the UMG Blueprint the Dispatcher should Update one progress bar and two Variables.

But for some reason it doesn´t display any Variables also the progress bar don`t Update. Another thing, that I wanted to mention is that I tested the whole system before in another project with the same settings and there it worked fine. So I would like to know how to fix that Problem!

Thanks
