Debug Message not Showing in PIE

Recently decided to try out UE4 so I can try to make a game. I followed this (https://docs.unrealengine.com/latest/INT/Programming/Tutorials/FirstPersonShooter/2/1/index.html) tutorial to try to understand how to create movement, characters, etc. I followed all the steps correctly but since the tutorial is a bit old I find some things different (such as GameMode being named GameModeBase instead) and Im not sure if this is also a contributing factor to the problem. The problem is that when I try to display a red debug message on screen on the top left corner as seen in the tutorial, it will not display it. I followed all the steps correctly and nothing will happen. The yellow debug message from the previous steps show as intended but the red one does not seem to show. If somebody with the same UE4 version can follow all these steps try to find a solution and post it here, it would be great. Since I am also new to UE4 programming, an explanation as to why it wouldnt work and the explanation as to the fix would be great aswell. Sorry if Im sounding very demanding but as I am still new to UE4, Im trying to learn the code as best as I can. Thank you

Fixed the problem with a restart of UE4
