Purchase invoice line standalone keeps creating invoice instead of lines

I activated the module but when I create purchases and receive the shipments, it creates the invoices rather than invoice lines. Is there anything that needs to be turned on/off to use this invoice lines feature?

IN newer series you need to activate the creation of the standalone invoices on the party form.
Otherwise the module will keep the default behaviour.

Hope this helps!

Yeah, I checked the Purchase invoice line standalone label, and it worked.
