Thanks for your question. Yes, the Unmanaged value in the snapshot and the breakdown by module should be the same.
There was a rare bug in the original build of ANTS Memory Profiler 8 (188.8.131.528) which exhibits this behavior, and we think this is the problem you are having.
I've just released a new build of ANTS Memory Profiler 8 (184.108.40.2060), which should correct this bug. Can you try the new build and let me know if you still see the same problem, please?
You should be prompted to download the update when you next start ANTS Memory Profiler 8.
