Thank you for your advice. I am a long way out of my comfort zone on this and appreciate your patience.
I have removed the sub domain, and focus on the root domain.
Therefore I will use the A record IP address in the domain IP address 83.136.248.56, and emove any other A records and CNAMEs in use.
Thank you for your support. I sincerely hope this will not cause additional problems but resolve the problem.

Yes - that should do it. Though I would keep an A record with 83.136.248.56 for the www subdomain, as that's pretty much standard and what people will expect to see.
Thanks
