I recently found the emergency call list, which can dial a number even when the screen is locked. I added a number from my contact list to test out how it works. After I figured out how it worked, I went to add 4 more numbers from my contact list, but I found out I could only add 3 total numbers. I deleted the first contact from my list that I used for testing purposes, but now I can't add another number on that spot, and also can't delete that number. When I tap the first spot, it will dial as an unknown number. How can I fix this? Can I get this first number to go away so I can add another number to my emergency call list?
