A file I have created on the smb share:

$ ls -lh /mnt/tank/media/test.txt
-rwxrwxr-x+ 1 janus writers 5 Jun 24 14:25 /mnt/tank/media/test.txt
$ getfacl /mnt/tank/media/test.txt
getfacl: Removing leading '/' from absolute path names
# file: mnt/tank/media/test.txt
# owner: janus
# group: writers
user::rwx
user:janus:rwx
group::rwx
group:writers:rwx
mask::rwx
other::r-x

The permissions are 0775 instead of 0660 specified by create mask. Furthermore, I don’t understand why it has a ACLs attached as I do not apply ACLs on the dataset.
