Need to change IP address in Dynadot A record

[Rayancaleb]

Hi,

I have an existing A record. I need to change its IP address. 
When I go to the Manage button and change the IP address, it gives me an error: Could not set DNS. Please set the "Email Forwarding Settings" to the "Do not forward email." option first.
I do not want to change email forwarding settings or MX records.
How can I just change the A record please?

Please help.

I didn't find the right solution from the Internet.
