NoN 2.5 was released yesterday as I saw on his Patreon. If anybody managed to see it can please let us know if is good? If yes I will consider to do an upgrade to my level and access it next week.
Not surprising. It's depends on the block-size since multiple files are under the same block (for 7zip), then one file just happens to register as having it all while all the others are missing or 0. Totally normal.
