email contact form in detail view

The Email field will only show as an email address.
To setup a contact form see: https://wpgeodirectory.com/docs-v2/integrations/ninja-forms/

You can adjust the options for the GD Ninja Forms widget to output as text.

For each item you adjust, try opening the advanced options. They are under the blue button.

For fixing styling issue you will need to write the custom CSS yourself or hire a designer.

If you meant the email value, that will always output as a link.
You can use CSS to make it so it isn’t clickable using the pointer-events rule:

.my-data {
pointer-events: none;
}

Adjust the Ninja Forms settings. Ninja Forms has a settings menu item. Adjust the styles there. Not inside the form itself.
