"Show Mouse Cursor" Not Working for Splitscreen

So, my team and I are working on a splitscreen FPS, and we are trying to make a pause menu for the game. We have the menu, and it works properly, except for the mouse visibility. The mouse always stays invisible, even after we have tried to set “Show Mouse Cursor” in the player controllers to true. We’ve even tried to set that for each of the player’s controllers, but it doesn’t work. We have tried the alternate Set Cursor widget node. Nothing has worked. Our team is following this tutorial. Any help would be greatly appreciated.
