Character is standing behind a layer from the tile set

Hi I’m new to unreal engine and am trying to make my very first game. I decided to create a 2d jump and run game. I have already created my tile map and several tile sets. But when I try to start the game the player is disappearing behind one of the layers that I made in my tile map. I don’t know what to do or how to solve this problem, maybe some of you already had this problem and could give me a little advice. (Sry for my english btw :))
