No transactions for purchased items in inventory value report

I'm trying to use the report under:

Inventory management\Reports\Status\Inventory value\Inventory value

The situation is that for the items we consider as manufactured items manage through the production module, the report is showing information. But for purchase items, no transaction (purchases, journals, invoices) is shown at all.

I've read many post trying to find the clue or the reason for this behavior but everything seems to be in order, I don't know what I'm missing... here there is a comparisson between item config that shows info and other item is not shown.

Many thanks in advance everyone that can help
