reseller with multiple web servers cannot assign them to a client

Just tested again (see forum: https://www.howtoforge.com/community/threads/reseller-add-client-web-server-not-available.75314/)

• Created new reseller
• Added 3 servers to his limits
• Login as reseller
• Create new client
• Limit of new client is only showing 1 server

When the reseller creates a website (not as user, as reseller) he can select any web server assigned.
