Some Event Management Template not sync to CRM by Approved Document sync from Vault.
There is no error on Approved Email Admin page.
One possible reason is that Vault Presentation WHERE Clause using the field crm_product__v to filter.
The vault do not use crm_product__v at all. crm_product__v is a different field than product__v.
product__v should be used for product filter.
Correct where clause: product__v = 'UP'
