Newly Synced SFDC Fields Appear Empty.

I have recently synced a few fields from SFDC to Marketo.  I can see the fields under the Filter options, however, I look under schedule, it always says the campaign will effect 0 leads when it should say anywhere from 500-2000.  The field I am trying to use is "Has Product."  Is this just a matter of waiting or am I missing something?
