Field in parent object returns undefined in custom compone

e.g. Getting the Industry of an Account from a Contact record.

Where ‘modelName’ is the model and ‘tst’ is the field chosen in the properties(Account__r.Industry). 
I have verified that the field is included in the model.

I am able to get around if by creating a UI-only formula field that references the desired field.

Has anyone else encountered this same issue? Or am I using the incorrect method to get the value?
