This might be a bug: I define material resources and work resources in arbitrary order and use them in tasks. Some of the materials behave sensibly, with no days (inputting zero to the duration column) the material price shows up in Cost column. Some of them require me to input one day to show up to show up the cost. Their work however remains zero hours. All materials are similarly defined in resources. This sounds weird.

Is there a dedicated bug reporting method for ProjectLibre?
