WPMUDEV Hub - Multiple Domain Names going to one Source

When my client purchased his website - be bought a package of similar domain names:

jgmcpa.com/jgm

http://www.jgmcpa.com/jgm
jgmcpas.com/jgm

http://www.jgmfunds.com/jgm
jgmfunds.com/jgm

http://www.jgmfundservices.com/jgm
jgmfundservices.com/jgm
They all get forwarded to 1 single Wordpress Install.

Whenever I go to the WPMUDev Dashboard Hub - I see all the Domain Names.
I would like to only see only one singular Wordpress site.

I’ve tried multiple times to delete the Extra Sites - but they always come back.
Any recommendations on how to tackle this?
