Sage Not auto-deleting (Shares? Settings?)

[Tomahawk51]

I'm using a Win VM on Unraid (not Docker). I'm finding that Sage is not deleting shows like it used to when on a dedicated Win client. Unraid tells me routinely that the HD I dedicated to a Sage Share has filled up, and I then have to go on a purging campaign (which the UI doesn't make too easy). I think it has to do with how I've setup Unraid Shares, or Sage Recordings. Any help?

Current Unraid Share Setup:
-Dedicated Share to Sage
-Minimum Free Space = 1gb
-Included Disk = #5 (of 5 disks I have)
-Excluded Disks = 1,2,3,4
-Don't use Cache Disk

Current SageTV Setting:
-Video Recording Directory = Folder in Unraid share, Diskpace Usage Rule = "Use All DiskSpace"

I would try telling sage to leave a couple GB free (I usually use 45GB as my free space buffer, but that's to allow room for ripping blurays and such onto the drive).
