Zsign Issue : trigger "document signed" and action "Send request by email"

Hello, 
i want to send a signed document to a backoffice email and it works but with sending two times the same email.

does somebody know that problem 

I've  created two Flow jobs :
1/ CRM trigger New module entry (deal)  --> ZSign action "send document" using a template and the customer email
2/ Zsign trigger "Document signed"   --> Zsign action "send request by email"   to backoffice email

--> 2 identical emails received with the good document ...
