When using the built in form tools on a layout Grid and using the built in form processor I leave the mail engin on default then after I save the work and close all the open boxes and go back to the grid and then if I re open it again the mail engine has changed from Default to PHOMailer - SMTP and the form fails.
How can I get it to stay on Default which works.

You most likely enabled another option which requires PHPMailer.
For example, if you select Rich text format.

If you need further assistance then please share a DEMO project, so I can see what you have done.
