I have found that domains added as a subscription work when I try to install to a specific domain via the dropdown list in Softaculous.
But when a domain is added to a subscription using the add new domain button in the Plesk Control Panel in the Websites & Domains tab, the domain shows up in the Softaculous dropdown list but if I install to that domain the installation goes in to the subscription's main domain and not the added domain.
Can you open a ticket and we will have a look at it.
