Transaction Replication issue

Hi, 

I configured replication in our SQL 2012 instance. The snapshot agent executed successfully, but facing the below issue in Distribution agent from distributor to subscriber. Everything is fine, I am not sure where the issue is, Can you please help me. 

Message: if COLUMNPROPERTY( OBJECT_ID('MSreplication_subscriptions'),'distribution_agent','AllowsNull') <> 1 BEGIN alter table MSreplication_subscriptions alter column distribution_agent sysname null end
