RN104 on 6.9.5 - SMB Doesn't Load (problem in smb.conf)

So I recently upgraded the firmware from 6.7.5 to 6.9.5 and also did a drive upgrade, exporting a volume, re-importing it and various other things that have led to several reboots of the NAS. But basically after the second reboot, SMB wasn't loading anymore. I could select it in the Management Console and check the boxes but when I checked the status ("systemctl status -a smb") I'd get:

 [2019/03/17 04:00:22.733065,  0] ../lib/param/loadparm.c:1121(lp_set_enum_parm)
 WARNING: Ignoring invalid value '(null)' for parameter 'smb encrypt'

I found a thread on here that says I need to change that to "smb encrypt = default", and sure enough, it then would load smb (after "systemctl start smb" of course). However this is temporary as the file seems to be auto generated and each boot of the NAS reverts back to the problematic change. 

Anyone have any idea what I need to change/fix so this doesn't get reverted on every reboot?

Or, anyone have any suggestions on how to build a timed script to make this edit in the file on reboot, but after the failed attempt is made (just concerned of a race condition).
