After Replication SEPM Partner Not Updating Defination

We are using 02 SEPM servers in Load balancing mode in Headoffice

We recently install and configure 03 SEPM servers in three different branches in Replication Mode

After Installting we found that Headoffice SEPM is able to syccessfully download and update clients

In brances SEPM download the definations but unable to update the SEPM

In Replication settings at branche site when I enable "Replicate client packages and Live update content..." SEPM in branc office updating the SEPM and clients

But problem is everytime it replicate content from Headoffice is around 512MB to 1GB (depends on content revisions)

Symantec still unable to solve my problem.

Hope someone can help me to resolve this issue
