Debian Stretch is EOL and used (if I remember correctly) Samba 4.5.16 
The latest Samba is 4.20.4 and 4.21.0 is nearing release.

If you are hitting a bug, then you have no chance of getting it fixed,
indeed it may already have been fixed in a later version, so I suggest
you upgrade both Samba and your distro version.
