Understanding ZFS Replication ... not all data synced?

I have setup a ZFS Replication of 2 datasets on my NVMe storage to my HDD ZFS array - on the same Truenas Host.

I backup the following datasets with all child datasets:

nvme1 > docker
nvme1 > exchange

to the following destination

hdd1 > backup > truenas > docker
hdd1 > backup > truenas > exchange

Now this is scheduled to run weekly and all seems fine in the GUI:

When I now check the contents of the datasets (hdd1 > backup > truenas > docker) it is not the same. The initial backup went fine but files that I added / changed in the last couple weeks do not appear in the backup.

I even tried to run NVMe Backup manually ... with success message ... but the files in the backup dataset are not up-to-date / the same as in the source?

Try making two replication tasks. I noticed you had both paths listed with a comma between them, thats the only thing that stands out as potentially unusual here

I resetup everything ... but seems normal that format with "," because I selected two folders:

And the setup looks good:

... but when I check sample files .. the test changes I added in a .txt are not updated ... although the snapshot runs every week.
