MS SQL Server Merge Replication blocking

I have a merge publication set up that is causing long blocking during the "create trigger" events for the merge process. For example, the head blocking chain is always something like this:

create trigger [MSmerge_ins_73FFF4AC9F4049E49EA08EF1CE3A797F] on [database].[dbo].[table] for insert as...

OR

create trigger MSmerge_upd_E6C5582E4B6A4B0099416548B5C615A0 on [database].[dbo].[table] FOR UPDATE AS...

What could be the issue? OR how do I troubleshoot what is going on.
