Title slug conflict between 'North and South' and 'North & South'

[SonarrNZ]

Sonarr version (exact version): 2.0.0.5344
Mono version (if Sonarr is not running on Windows): N/A
OS: Windows 10
Debug logs:
Note, I cleared the logs before generating the error and the following is all the log contained after the error was generated:
*20-4-10 10:25:10.9|Warn|NzbDroneErrorPipeline|Invalid request Validation failed: *

• – Title slug ‘north-and-south’ is in use by series ‘North and South’*

Description of issue:
I have three similarly named TV series:

1. North and South (1975) (https://www.thetvdb.com/series/north-and-south-1975) [TVDB ID: 287409]
2. North and South (https://www.thetvdb.com/series/north-and-south-1) (1985) [TVDB ID: 81645]
3. North & South (https://www.thetvdb.com/series/north-and-south) (2004) [TVDB ID: 79321]

I have successfully loaded ‘North and South (1975)’ into Sonarr, but regardless of which order I attempt to add the remaining two TV series, I receive the ‘Title slug’ error specified in the debug log.

This issue has been raised in TVDB (https://forums.thetvdb.com/viewtopic.php?f=25&t=51157&p=138283&hilit=north+and+south#p138283) with the suggestion to ‘add the year to the series title’, This suggestion received the following reply:
The first has a year, to set it apart from number three. The second has a different title (and instead of &) and doesn’t need a year.

Is there a solution/workaround in Sonarr? If so, what is it?

Thanks in advance for any help.

I made a change in Skyhook (our TVDB proxy) in order to override the generated slug, it should be good in the next hour or so when the cache expires.

Thanks so much. All working as expected now.
