How to disable "suggested contacts" when adding a new contact

[AC Question]

Hi guys!, this issue is driving me crazy a bit. I have a Samsung galaxy s7 edge, and I cannot find anywhere the solution to this issue so I'll ask it here, may be you can help me: each time I want to add a new contact, and I start to write the 1st letters, it appears above the contact's name the suggestion of contacts that already saved. For example if I start to write "Fl..." it appears above it "Florencia Rami", "Florchu Gonz", etc. I don't want this behaviour to happen. Each time I add a new contact and the person is looking at my phone he can see some contacts I already have saved, I don't want this at all, it's kinda uncomfortable. How can I disable this behaviour?. I save the contacts in a gmail account.

Any help will be appreciated. I

Have a wonderful day!.-
