Your Domain does not use ISPConfig servers; according to your screenshot, it uses OVH servers. So you can not create the DNS zones in ISPConfig as the authoritative DNS server of the zone is at ovh. Besides that, you added a subdomain of the zone that's managed by OVH as a secondary zone, this can't work and makes no sense as you would add a domain you want to provide secondary DNS service for there. Maybe you should familiarize yourself with what DNS is and how it works, as such basic knowledge is really helpful if you want to run your own DNS servers, and this is also not ISPConfig specific. Also, @Taleman has a detailed tutorial on how to set up a DNS zone in ISPConfig: https://www.howtoforge.com/tutorial/setting-up-your-own-name-service-with-ispconfig/
Maybe you should consider to just stick with OVH name servers for the start and wait setting up your own DNS servers until you are more familiar with DNS. You do not need your own DNS servers to host websites and email.
If you want to create a secondary DNS zone for gifts-custopolis.com, then you must first create a primary DNS zone for gifts-custopolis dot com in ISPConfig on the primary DNS server, and then you create a secondary zone for it on the secondary server. as this secondary zone is for gifts-custopolis dot com. you must enter that zone in the zone field, in your screenshot you entered the secondary DNS server hostname there instead.
