[Question] Luks container mounted on multiple devices via network

I have a 50GB container stored on a NAS I've been using for more than
a year. Today, I needed to mount this container on multiple devices
(Debian, Kali and WSL), and I had no problems, until I noticed that
the files transferred from DEBIAN to the container were not displayed
on KALI and WSL. I unmounted the container on all devices and
remounted. The files are there, but I can only see it on the device
that saved the files. All devices are using the same version of
cryptsetup.

Is that normal? Am I missing something?
I'm backing up all the files, and I noticed no damage to the files.
