This seems to happen randomly after creating a multilayer board. Here was my procedure for restoring it. Go into properties and uncheck "set a default". Delete your board outline. Create a new board with the wizard that is 2 sided. Ignore the what the layers say at this time. Go back into properties and re-check "set as default" and then close the board. Close Ultiboard and then re-open it.
This should clear it up for new boards. If you already have a board made with this happening then I do not at this time know how you would correct that. I will look into it and see what I can find out.
This situation is hard to re-create and it took me a few time playing around with the multilayer to even get it to do it. NI may need to look into this and see if they can find what is causing this and a better solution to resetting back to the defaults when something like this happens
