Only the campaigns the constituent has given to appear on Revenue and Recognition History tabs campaign filter list. When moving from one constituent to another, if the second constituent has given to a sub campaign the first constituent did not give to the sub campaign is not checked in campaign filter.  This is misleading.  Unless you review the filter there is no way to know that not all sub campaigns have been selected.  One would assume if you select a main campaign all sub campaigns would be selected no matter which constituent you are on.
