Problem Sync only in one direction

I would appreciate help with synchronization issues

I currently have a WD my cloud EX2 Ultra
The installation consists in:
1 computer desktop (DT)
1 laptop (LT)
1 Wd myclud Ex2 ultra (MC)

What I want is to have a folder synchronized between the Desktop and the laptop in the style of gdrive

What is done:

I have installed WD Sync in Labtop and Desktop

we have dfefferents Folders:
In Desktop: Local Folder–>CS_DT WD sync folder–> CS_MC
In Labtop: Local Folder–>CS_LT WD sync folder–> CS_MC

It synchronized in the way that a file created in CD_DT got a copy in CS_MC but not in CS_LT
It synchronized in the way that a file cretaed in CD_LT got a copy in CS_MC but not in CS_DT
if i create a file in CS_MC i dont get a copy in any place

Something I do wrong but I can not find out what it is.

Thanks in advance
