Why am I unable to customize contact labels?

[iMore Question]

When trying to enter relationship for contacts there are only 3 options. no option to a custom labels. Under Label there is manager, spouse or assistant, Yet with the contacts that were transfered from my 5C there are other labels that I was able to add. Those contacts were transferred over but with new one I don't have that option.
I'm not really iphone savy so need help.

Iphone 6s i cannot customize relationship labels.

I just created a fake contact called John Doe and was able to select from an extensive list as depicted in the below screenshot. You can resetting all settings to see if that helps.
