How can we set up unique names for our same language interfaces?
Interface labels, All versions
When trying to set up unique names for our interface labels, the label name appends to all the interfaces which are in the same language.
Labels are language specific. This is an expected behavior as it is not possible to have different label names for two or more interfaces which were created in the same language.
In order to have different label names for your English interfaces, you can set up one interface in English (US) language, another in English (UK) and a possible third one in English (AU).
However, for the other supported languages, like Chinese (which has 3 language packs), you will not be able to have different label names for each interface as there is only 1 available language pack per country.
1. Changing the label of the primary interface will also change the name of the record you are updating (e.g. Profile name, Social Channel name, Customizable Menu name, etc.). If all interfaces are in the same language, changing any of their labels will also change the name of the record in the same way.
2. Changing the name of the record will also change all default Labels from the interfaces, no matter the language in which they are configured (except the labels which have already been manually updated before changing the name).
