1) You have production modifiers. Let's say you have 10% to buildings, and all your cities are producing buildings. It means your manufactured goods are showing that 10% gain, which will be lost when you go to the world congress project.
I know also some policies will affect it (like Artistry opener), but this wasn't the case as my production was fine.
2) Production overflow. If the turn before the world congress project, the AI (or you) finishes a building with 50 spare production, it passes that production to the next item. On high difficulties, the AI tends to be overflowing a lot of production turn for turn.
That sounds like the reason. It tends to happen almost exclusively on the Treasure Fleet project which often gets done in 1 turn - so the production doesn't have time to stabilize. I will probably stop proposing it since it happens almost every time (up until the late game where the project does not matter), but is a shame.
