Unfortunately I don't seem to be able to reproduce the bug. If you are able to get me your save then I'll be able to diagnose it fairly quickly to figure out what is wrong.
Edit: My apologies, I didn't even answer your question. I made sure during the update that the longevity training is applied directly to your maximum lifespan rather than slowing down the rate that you age. The newer training is also supposed to apply gradually as you complete it rather than only giving you the years at the end. Any completed training from before the update should have been carried forward as well.
