Changes are detected even if I change nothing

Hallo,

I don’t understand why Kopia is seeing changes in my files.
In each snapshot, there is 306 files but when I run it again and again, Kopia will see
the differences below.

Why?

Note: I’m making a mount of Google Drive via Rclone and I run a snapshot on it.
The inode stay the same, I don’t unmount, mount again, same size, same last modification time …

Ok this is because Google Drive does not support native format export. The gdoc files needs to be created in another format (docx, xlsx, …). And boom, the content is not the same.
