Removing Paint on Landscape Mode

Hello fellow users of UE4. I’m quite new to the game dev community let alone any type of 3-D software, so please bear with me here. I’ve recently come across a problem with the painting in landscape mode. I’ve been trying to remove paint from my landscape but it hasn’t been working for some odd reason. It says to remove paint the controls are Shift+Left Mouse Button. However, I’ve been trying that and it hasn’t been working. Can anyone help me out here?
