Issue with dns configuration..

I think I have problems with configuring DNS, or I did not understand the right way to configure it.
This is my situation:

VPS with 1 satitc IPV4
(at the moment) only 1 domain (OVH registar) where i can manage dns settings.

What i do.
In ovh i setup
mydomain.com A (my vps ip)
srv.domain.com A (my vps ip) //srv.domain.com is my hostname
www.mydomain.com CNAME mydomain.com
mail.mydomain.com CNAME mydomain.com
webmail.mydomain.com CNAME mydomain.com

I created a domain named "mydomain.com" and it works.

Now i need to create a subdomain "test" -> test.mydomain.com
i created it but i can not reach it..... i can reach it only adding in  OVH (my registar) test.mydomain.com A (vps ip) or test.mydomain.com CNAME domain.com

is it normal? isnt possible to let cwp to manage the dns? how can i do that?

I expect you have sorted the problem now but dns was confusing for me until i got my head around it all.

I used the free dns manager on cwp and it was ok but it is a lot easier for me to use cloudflare for dns and just add their nameservers to cwp.

I have three A records for naked domain, www domain and hostname pointed to my vps IP and then a few more mx/txt records for my email hosting provider.
