iOS scripts across devices,doesnt recognise elements

Something very wierd, i am using iPhone 6 V8.1.3 and iPhone 5 V8.1. Installed same app in both the devices.

While trying to automate the Login screen,i captured elements using “iPhone 5” for username field and capture d elements for password filed in “iPhone 6”.

Now same elements [xpath], username works[i.e username field is recognized] in iPhone 5 and the password field is not recognised by iPhone 5 saying " element not found". Vice versa in iPhone 6

I have to confirm whether its an issue with Appium [V1.3.5]… i am pretty sure that my script is very basic and has no errors.
