FYI, it is not possible to convert EDU to Commercial file nor it is permitted under the EDU license. If you open a EDU file in Commercial it will switch to EDU mode.
-----
Another option to save selection is to select what you want and save as a module (.mod) then you can open this file and save-as a regular .pln
Though it will have the same problems as copy/paste between EDU and Commercial.
