edit page show_key1

Seems to be different behavior from 4.2 to 5.0 on edit pages. In 5.0 in the header I get [rowName: show_key1]
It display table column name and id (show_key1) for the row that is to be edit. This would be cryptic to the user and just add confusion. More value would be something in the header that would display on the edit page something about the record that would make sense to the user. I hide primary keys from displays mostly. I can delete the code from the custom template. Just an observation.
