Duplicate/Triplicate contacts in Mautic, connected with Pipedrive

I have my Mautic account that imports the Pipedrive persons. The major part of my contacts appear duplicated. The first is only created. The second one is created and updated. The two contacts are created at the same time.

Also, if I actualize a contact in Pipedrive, it only updates in one contact in Mautic (in the second one).

I tried with only the unique key of email, also with unique keys as Phone, email, IDPipedrive. All my contacts have email and Phone.

I also tried with Updatable contacts and still does not work!
Also sometimes there are contacts that are created 3 times, and some that are only one 1.

What can I do?
