there is lots of fields like the one you mentioned that contains a lot of data or will take too long to query the database and won't render results after the searching has finished.
Unless you know specifically what your looking for you can add the text.
Hi Ed -
Was any progress made on this? I am having a similar issue, and this is not a case of excessive data - Role is defined in SFDC, but the contents of the field are not carrying over to Marketo. There is a Role field, but it is blank.
My SFDC Admin assures me that permission are set appropriately. Any idea what could be causing this lack of data?
Was this ever resolved? I'm having the same issue. I don't think it's an issue of the picklist taking too long to load. My smart campaigns don't seem to be "seeing" the contact role roles.
