Asset Hashes different between frontend and backend instances

I ran docker-compose and brought up containers using pwd.yml.
I, then, installed a the ecommerce-integrations app on the backend instance using bench install-app.
I, then, ran bench build on the backend and frontend instances.

Then problem is that the generated css files have difference hashes on the front and backend instances. Any idea on how i resolve this issue?

Build custom image to use custom apps.

Thank you
