When entering a new quotation for sales, I used to be able to enter order line info by clicking on "Add an item" and searching for a product entering the information directly. But now, suddenly, if I click on "Add an item," it throws a pop-up to a new screen, "Create Order Lines."

On the purchase module, it works fine; when I click "add a product," a new line is created, and I'm able to type inside it to search for a product.

Does anyone have any idea how to solve this problem?
