XCode UI Test not detecting UI element every time

Recorded an UI Test in Xcode 8.1, it runs perfectly for the first time but when I run multiple times it do not detect UI element. Reason showed is either

"Multiple Matches found" or "No Matches Found"

I tried using "debug description" and "Accessibility Inspector" for checking hierarchy but it is of no use.

Logs are saying "Using Cached Hierarchy", does that causing error?

As I am new to UI Testing, Please Help..

Thank You!
