Issue Description
When trying to reference a Custom Object in a Smart List with a Filter, there are no filters for the Custom Object. Yet, when checking within a Smart Campaign, there are Triggers for the Custom Object.






Issue Resolution
Filters are not included in the original design of the Marketo Custom Object setups that act as an intermediary/bridge between two other objects.

Check the object setup within Marketo Admin > Marketo Custom Objects - how many linked objects are there? If there are two linked objects, that means the selected Custom Object is an intermediary/bridge between the two linked objects. For these, there will not be any Filters, however there will be Triggers for these objects.
