Duplicate Note in picking group

[GuillermoBonet]

Good morning,

we have a client in v16 that has a problem with module account_invoice_report_grouped_by_picking : when the invoice has a note line, all picking that are down this note line in the sequence, introduce this comment. I did a pull of the 16.0 branch for take a look if there are a solution, but the error persist. Attach images about the example

In this case we see a comment in the middle of lines because this comment is in one specific picking.

This image show all lines that are after the note.

The last image show all lines that are before the note. As you can see they don't have the comment.

Are someone working in this bug?

Thanks for your time.

best regard
