Question Control scheme locks into using controller only

My game uses three control schemes. One for controlling the main character, one for using the UI, and one for using the level editor mode that I added. When I'm controlling the character, and my controller isn't plugged in, the keyboard and mouse work fine. However, when my controller IS plugged in, the main character only accepts input from my controller, and doesn't respond to the keyboard and mouse.

What makes this especially weird is that when I'm in level editor mode, suddenly all three devices are accepted. It works as intended. This problem only occurs when I'm controlling the main character.

What am I missing here?
