Custom related fields' labels reset to default

Hi,

My custom related field labels constantly revert back to default?
e.g. Husband Name = Contact   or   Practitioner Name = Contact

In this example, Levi's field is related to his Wife's contact record.



As you can appreciate, things get very confusing within our instance as more and more custom related fields are added (not to mention within the Admin back-end...Which field is that again?!)



A non-code solution or suggestions would be hugely appreciated if possible.

Using Pro 6.7.5 On-Demand.

Cheers.
