How do I prevent the SRV from appending the domain?

I’m attempting to deploy a matrix synapse server on an ubuntu 16.04 droplet. The network and domain are being managed by DO and I’m trying to remove an error from MY DNS SRV record.

TASK [matrix-base : Fail if DNS SRV record incorrect (Ansible dig lookup)] ********************************************************
fatal: [matrix.mtx-me.tk -> 127.0.0.1]: FAILED! => {"changed": false, "msg": "It appears the DNS SRV record for _matrix-identity._tcp on mtx-me.tk. is not set up correctly. Expected it to point to `matrix.mtx-me.tk.` (port 443). Found it pointing to `matrix.mtx-me.tk.mtx-me.tk.` (port 443). See the 'Configuring DNS' documentation for this playbook."}

I’m entering “_matrix-identity._tcp” for the hostname and “matrix” for the redirect into the SRV record creation screen. I’ve tried adding a dot at the end to prevent this but no joy.

Thanks!
