When trying to set MX record for a domain in WHMCS 5, priority isn't working properly.
Example:
I entered 10 value in "Priority" box and here is was I got after saving the changes:
@ | MX (Mail) | 100 mail.secureserver.com | _
(see attachment)
And when I tried setting priority as in previous version (entering priority in "Address" box), it worked.
