Enfold Contact Form – how to cleanup sent message from code snippets

Hello,
I am using the Enfold contact form with Avia layout builder. There is only one checkbox in use for the acceptance of our privacy statement. The site is for Germany and therefore it has to show a link to our privacy statement.
So I used the following content for the checkbox element:
Ich akzeptiere die Bestimmungen der ###lt###a href=”/datenschutzerklaerung”###gt###Datenschutzerklärung###lt###/a###gt###.

This works well and no error is displayed. But when sending a message via this form, then I receive this at the bottom of the email message:

Ich akzeptiere die Bestimmungen der [/datenschutzerklaerung]Datenschutzerklärung.: true

How can I clean this up? I do not want my customer to receive such emails. It has to look well and not like bad styling.

Best regards
Bettina
