Wrong Settings folder in backup

Just performed an upgrade from 17.4 to 18.2. I’m using user settings for the data file and the Settings folder with the backup settings is next to the data file. I added the Settings folder to the backup using the “Add Folder” button and looks like the following in backup settings:

<IncludesFiles>
  <ItemsCount>3</ItemsCount>
  <Item1>drive:Data:4d:map:Map.4DIndx</Item1>
  <Item2>drive:Data:4d:map:Map.Match</Item2>
<Item3>./Settings/</Item3></IncludesFiles>

But looking at the backup log file, it is apparently backing up the Settings of the built server:

"attachments": [
				{
					"attachmentPath": "drive:build:18:Client Server executable:Map Server.app:Contents:Server Database:Settings:",
					"found": true
				},

I modified the file to use a full path, hopefully that will fix it for the next backup. But it seems like a bug.
