Import/Update layered solution from environment to other - Language issue

[lbamrtn]

Hello,
I have project accelerator solution in 2 environments (with project service core and accelerator installed).

• Environment DEV config in English.
• Environment TEST config in English.

I added French language in my environments. Downloaded translation file and imported French translation for my fields in both environment.

When trying to update solution in my test environment I have this error message : "Entity 3ed6cfb0-d3f6-4673-b071-ec3f9c9a81b9 is not a renamable entity. Hence Entity Display Collection Name cannot be modified."
Error code from my log : 0x8004023B

Entity refer to my project table, but I did not modify existing field, just added new ones.

Can someone help me :)
