Are you able to post some logs or screenshots showing the behavior you are seeing?

I am using SCCM 1806. there is a secondary server which has around 13k objects to manage<br />
<br />
each boundary group has its own DP so that client systems need not be download the contents from sec server<br />
<br />
on boundary group relationship I have set never fall back to sec server default group for content<br />
<br />
still some clients download the data from secondary site. total size of the data for 7 days is 1567GB. some of the clients has downloaded 8 to 10 GB from secondary site. can some one help me to understand the root cause of this?
