Extend Fiori Paystub- display name issue

Hello

We have extended the Fiori Paystub and hidden one field using WEBIDE. When we run the extended app it shows DISPLAY_NAME in the browser tab title for the extended app. It is not able to get the text "My Paystubs". All other titles seem seem to be getting the texts.

The standard app works fine and shows the correct Application name. The I18N file in the standard app has the required entry

DISPLAY_NAME=My Paystubs. Any ideas on what the issue could be

Thanks
