AE to Media encoder renders old deleted assets

I have an issue with media encoder, where if I change an asset in AE like audio and even delete it from the project, AME still renders with the old audio. Is it being stored in cache somewhere?  Is it in RAM do I have to restart my computer every time I want to render from AME? How do I fix this?

Side Note: I would be really great if Adobe could add the ability to render H.264 MP4's straight out of AE, instead of having to use encoder. I didnt have these problems until I had to use AME to render.
