Bug: edge export cost + error work open old file

I don't know if I am the only one, but:

1) when I import the edge csv the cost of work/mt is the same of the cost of the product, so I have to modify manually every edge product


2) sometimes, not always, when I reopen an old file, the work doesn't recognize, I have to search manually in list ( I don't for now a screenshot, I will make it when it comes the problem)
