4.18.1 IOS- No valid certificate found

Everytime I import the provision to my project, it keep showing this for me.
Can anybody help me figure this out?
I was follow the IOSQuickStart from Ue4’s Document. Also buy the Apple developer account.[link text][1]

I get this as well, on both 4.17 and 4.18.1
If I try to launch the game anyway I get: "LogPlayLevel: Program.Main: ERROR: AutomationTool terminated with exception: System.FormatException: Input string was not in a correct format."
