If your domain won't verify in the Oasis Software check the following:
Check that you removed it from Clickfunnels. If you haven't removed your existing domain from Clickfunnels follow these steps.
The only records in your Cloudflare account should be 2 CNAME records. If you see other CNAME records or A records, delete them.
Make sure you did NOT add www to the domain when they added it to the software.
Mare sure your CNAME records are set to the proxy status of "DNS only" in Cloudflare
If all the above is correct remove the domain from the software and re-add it again.
Note: It can take several hours to verify so wait at least two hours before contacting Support.
