Bug widget - no text after package

Hello,

Please excuse me for my bad english. I created a small application for android! This is my first game develop with Unreal Engine and it requires some optimizations but I feel really lost, I can not find where the problem comes from so I hope you can help me:

The game is an “endless runner” of the kind of flappy bird but with a plane. I added a widget “hud” with the score and the highscore. The highscore is only displayed when it has a value registered in the “highscore_Value” slot.

When testing in “new editor windows”, there is no problem but after the package, the highscore is not displayed and the score + hishscore on my widget “gameover” do not display either. Basically, bind the save values ​​are not displayed after the package
