Merge Replication Issue: The coulmn value ins_conflict_proc is null for sysmergearticles table

Hi,

We have merge replication topology with 15 subscribers and central publisher. After we added new article in existing publication, the entry for column ins_conflict_proc in sysmergearticles table getting missing at subscribers and have to create the same procedure manually and tehn have to add entry to it. This causes to slowness of merge replication.

Please Suggest the reasons for this issue.
