Canvas provides each Form Item with its own label text, which can be either the Display Name Key (i.e. property driven label text) or plain label (i.e., direct text).
Display Name Key
The Display Name Key is a property driven locale enabled label text.This label text prefixed by 'LBL' keyword must be available in the property file that is mapped to a bundle key. You can find existing or map new bundle key with property file in a JS file.
...
Consider a bundle key 'common' that is already mapped to property files common_en_US.properties, common_en_UK.properties, etc. To add label text "First Name" for the Display Name Key of ''FIRST_NAME", add 'LBL_FIRST_NAME = First Name' in common_en_UK.properties and common_en_US.properties files.
Plain Label
On the other hand, Plain Label is direct text, which is directly rendered without any translation irrespective of the end-user locale.
