Curious bug, scientists transferred to another base via buy and sell screen (OpenApoc feature) or transfer screen, whilst working on a project will leave the building as expected, however, they still appear on the count of scientists assigned to that building... even beyond building capacity
For example, in the screen below, a workshop with a max capacity of FIVE appears to have eight assigned despite only having five scientists assigned and despite the capacity of the building being five

Another example of this bug, so reopening, see attached save game
Base 1 Biochemistry has 11 scientists assigned despite only really having 10!

Did you load old save before the patch?
Ah of course, my mistake
Apologies
Ok good. You can reopen if there is still something weird happening in a fresh new game.
