halnavel, what names do you use for the form fields in CF7? Is it “name”, “subject”, “email”, etc. or something else? Could you attach a screenshot?

There is an easy fix.

1. Open your wp-content/plugins/contact-form-7/modules/flamingo.php
2. Go to line #112:
$template = sprintf( '[your-%s]', $field );
3. Change it to:
$template = sprintf( '[%s]', $field );
4. Now it’s fixed!

Same here
