UI doesn't appear on a specific level.

So my HUD ( score counter and item counter ) are well done in my character blueprint, and they work in almost every level except one. So idk why I have this problem ( in this level, the level blueprint is good, nothing is supposed to hide the HUD because I didn’t use any “remove all widgets” node )

This question does not have enough information to make it answerable. At the very minimum, you should show some blueprints of the code you’ve done for us to be able to provide some sort advice
