Christian,

At this point the LDM can't filter out the duplicates because they have
different sequence numbers. The current LDM filters duplicates on the
complete product including the sequence numbers. In the future, the LDM
will filter out duplicates on only the body of the product, so these
duplicates will disappear. 

Glad the data feed is working .

Robb...
