Nameserver issue

Hello guys i just installed (again) hestia on my vps, i created a user accont and added 3 domains to it. domain1 , domain2 domain3, i did the nameserver update on the registrar, which is on, however only domain2 and domain3 works fine, but domain1 doesnt work it doesnt resolve the dns, claiming it needs to create a A record for it but upon creation Hestia did create it. so not sure why domain1 is not resolving eventhought it has the A records, otherwise domain2 and domain3 wouldnt been working, so kinda confuse. let me know what doing wrong, thanks.

Have you made it as child-ns in dns section?
