These tables likely don't have primary keys on them.
First off check you can see them in query analyzer in the publication database.
select * from sys.objects where type='U'
Then check that they have PKs.
SELECT SCHEMA_NAME(schema_id) AS SchemaName,name AS TableName
FROM sys.tables
WHERE OBJECTPROPERTY(OBJECT_ID,'TableHasPrimaryKey') = 1
ORDER BY SchemaName, TableName
