Hi. I have identified 2 problems with this app (Version 15.0). 

Sometimes, when I enter weight for one product, the next product I need to enter weight remains with the previous capture. 
Some other times the next product (after the one I entered the weight) takes automatically the previous weight entered without showing the weight capture window.

Hello, how does the module work, when I add the same product twice, for example when I add 1kg of onion and then I want to add another 3kg. I can select the product again and it will add the new kg. Or is it necessary to change the amount of product already selected before?
