Hi @yoursanil3 ,
The <Debug> message next to the project name is related to the building of the project, the default building in MCUXpresso is Debug but, you can change this in the arrow next to the hammer of building


This will not cause any effect to your project.
If you want to know more about this, you can see section 3.1 A note about Launch Configuration files of the MCUXpresso IDE - User Guide
Hope it helps you!
