Graphs

If I make a box in one computer and then move to another computer, I get different results.Initial box made in my macbook and then saved, closed (created a new blank project), moved to another computer,opened a saved project, pressed Draw and got totally different graph. Which one to believe?

Moreover when I switch on Network, added HP filter 80Hz, got the result that does not start to roll off from 80Hz, can be explained that Helmholtz steps in but when I turn off the Network and/or remove the HP filter, the graph will stay as after adding a network and does not change back to original one like opening the project without adding the filter. 

It's not even a question but more like a bug report.
