Description of issue:
As indicated above, I’m getting this notice in the system information section of the UI. Here’s my paths:

Sonarr:
Root Folders
Z:\TV Series

nzbGet:
PATHS

MainDir
C:\ProgramData\NZBGet
Root directory for all tasks.

On POSIX you can use “~” as alias for home directory (e.g. “~/downloads”).
On Windows use absolute paths (e.g. “C:\Downloads”).

DestDir
Z:\Downloads\Complete
Destination directory for downloaded files.

If you want to distinguish between partially downloaded files and completed downloads, use also option InterDir.

InterDir
Z:\Downloads\Incomplete
Directory to store intermediate files.

If this option is set (not empty) the files are downloaded into this directory first. After successful download of nzb-file (possibly after par-repair) the files are moved to destination directory (option DestDir). If download or unpack fail the files remain in intermediate directory.

Using of intermediate directory can significantly improve unpack performance if you can put intermediate directory (option InterDir) and destination directory (option DestDir) on separate physical hard drives.

NOTE: If the option InterDir is set to empty value the downloaded files are put directly to destination directory (option DestDir).

NzbDir
Z:\Downloads\nzb
Directory for incoming nzb-files.

If a new nzb-file is added to queue via web-interface or RPC-API, it is saved into this directory and then processed by extension scripts (option Extensions).

This directory is also monitored for new nzb-files. If a new file is found it is added to download queue. The directory can have sub-directories. A nzb-file queued from a subdirectory is automatically assigned to category with sub-directory-name.

QueueDir
${MainDir}/queue
Directory to store program state.

This directory is used to save download queue, history, information about fetched RSS feeds, statistics, etc.

TempDir
Z:\Downloads\Temporary
Directory to store temporary files.

ScriptDir
${MainDir}\scripts
Directory with post-processing and other scripts.

This option may contain multiple directories separated with commas or semicolons.

NOTE: For information on writing scripts visit http://nzbget.net/extension-scripts.

LogFile
${MainDir}\nzbget.log
Where to store log file, if it needs to be created.

CATEGORIESView

Category1
Category1.Name
Movies
Category name.

Each nzb-file can be assigned to a category.
Category name is passed to post-processing script and can be used by it to perform category specific processing.

Category1.DestDir
Z:\Movies
Destination directory for this category.

If this option is empty, then the default destination directory (option DestDir) is used. In this case if the option AppendCategoryDir is active, the program creates a subdirectory with category name within destination directory.

Category1.Unpack
Unpack downloaded nzb-files.

For more information see global option Unpack.

Category1.Extensions
Choose
List of extension scripts for this category.

For more information see global option Extensions.

Category1.Aliases
List of aliases.

When a nzb-file is added from URL, RSS or RPC the category name is usually supplied by nzb-site or by application accessing NZBGet. Using Aliases you can match their categories with your owns.

Separate aliases with commas or semicolons. Use wildcard characters * and ? for pattern matching.

Example: TV - HD, TV - SD, TV*

Am I supposed to point nzbGet someplace else in the Categories section and then Sonarr (Radarr too) will put them in the desired location for me?

Yes and ideally on the same volume so moves are atomic.
