Package transfer is successful but source code files are not transferred

Hi Team, 

Critical issue -

We are transferring our package from dev to prod site and package migration is successful but source code files are not transferred from dev to prod - 

In dev site there are total - 35 source code files


But in prod only - 25 files. 



Package migration is not throwing any errors its always successful but when I see the application hub I noticed that it only shows package with timestamp till 12 June 2025



Can you please help us why is this happening in the system?

Thanks
