It's a nasty business, but sometimes no one has answers for questions like those.

Future Imperfect is set before The Invasion and ends with the Doctor being sent into the events of The Three Doctors. And yet, in that story, the Doctor recognizes UNIT. The Eight Doctors has many of these "midquel" adventures, and most of them have notable continuity issues. It's a standard at this point.
