Nextcloud et ZimbraDrive: having same files in the two interfaces

Hello all
I’ve installed ZImbra 8.8.15 and NextCloud in my ubuntu server. I’ve set the too of them to use same login and same password.
My problem is that when i’m connect on my zimbra webmail and go to zimbra drive, i dont see the same file that when i’m connecting to nextcloud interfaces. However, i check the file on the server and there is only one folder for the user, and files are in this folder with the same rights.
Anaybody had this problem and found a solution ? what data do you need to help me ?
thanks in advance for helping me and sorry for my english if there some grammatical or others fault :wink:
