Number of parts is different

Hi,

I’m using dynamo to material take off.
I saw something estranged, so i’m looking for.

Look, when i selected all my project, and filter, there is 713 parts.

If i isolate all parts and select, also is showing 713 parts.

BUT, when i make a parts list in dynamo, is showing 896 parts.

Have you ever seen this?

I think i got a difference.

When the parts are divided, look what is happening:

Like i have a part, then i divide this part in 2 pieces.
So one is excluded and the other is the parts that i want.
But the part before to be divided still in the list.
