EFS FileSystem not updated

[castaf]

What happened?

I create a FileSystem MR among other MR from a XR. The creation of all MRs succeed, and my XR is "Ready" and "Synced" (as well as the FileSystem).
When I update the parameters of my XR (FileSystem throughputMode, or FileSystem backup), my XR is ready (also the FileSystem MR) with updated parameter values but the external resource EFS FileSystem stays unchanged : throughputMode or/and backup parameters are not updated.
The FileSystem MR Status values are regularly well updated.
The external resource EFS FileSystem and its dependencies are well deleted when I delete my XR.

How can we reproduce it?

Spec of the EFS FileSystem:
