When a main domain is disabled, it takes all the subdomains down with it, regardless of whether the subdomains are hosted by us or not. What I have done is removed orcagroup.top from your account and left the subdomains. If the subdomain's MX point to us they should stay enabled, and if the main domain isn't attached to the subdomains it won't take them offline too when it's disabled. If you decide to host the main domain with us some day we can just add it back to your account.
I created a full backup before I changed anything which you can download from https://heliohost.org/backup/ in case anything got lost in the shuffle. KazVee has written up a nice guide on how to extract the full backups if you need help with that too which can be found at https://wiki.helionet.org/tutorials/plesk/account-backups
