There is 2 contacts in the same CRM but they do not match !

It is in the title :  There is 2 contacts in the same CRM but they do not match !
I turn to the forum to try to get help. I ask the regular way. Without answer, I turn to the escalading demand. Same : no proper answer…
Zoho seems full of promises but so many flaws. 

This one is very interesting :
Within the Zoho CRM, there is 2 different contact lists. That's great, but the trouble is that they don't match…







One has got 7 contacts and the other has got 200 and that are not even the same contacts…!


I could also show you the difference still in the same CRM, between 2 differents access to the email : one is E-mail in the menu, the other is a paid item called Mail Magnet. It is similar : they do not match !!

Any idea to help ?

I am very lost. I do thing it is either a bug of intallation in the complicated process between the modules of Zoho.
