Campaing's "Send email to user" action, loose setup (email to and email template) details after database string replace

My Mautic version is: 2.16.1
My PHP version is: 7.0.33-0+deb9u6

Steps to reprocude the issue:
1 - I have replaced a string inside the table as bellow.

UPDATE campaign_events
SET properties = REPLACE(properties, '', '')

2 - This is just a simple e-mail address replacement.

My issue: After I replaced it all the campaings who used this email have lost (send email to user) action configuration. Bellow is a explanation of which setup was lost.

Could you please, someone, clarify me why it happens and what should I do to make this replacement without loose campaing actions setup?

Thanks in advanced.
