Well, then there's a bug, because when I'm researching something I can still upgrade any labs that I did not start the research on.

Pretty straightforwards. I know you can't upgrade the research lab while you are researching something, but I can upgrade a different research lab on a different planet. Maybe this is intentional but I thought it was worth pointing out.
