MSDP Duplications not showing data

I had been having trouble with SLP duplications between MSDP's in different data centers a while back. We decided to turn off the replication in order to work other avenues as our support case was open for 6 months and no real progress was made.

I have recently decided to turn reenable the SLP's and troubleshoot the issue a bit more for my own knowledge. I am noticing that the duplication jobs are completing and there are images on the secondary MSDP in the catalog.... However, for the duplication jobs I do not see a vaule in the KB field. I was wondering if this is normal or not.
