It is tracked based on a hash for the file (no we don’t track where the hash came from). A possibility is if the info for a specific hash is wrong due to an earlier version of the algorithm, and it gets reused. That’s why I’d like the OP to check if the cloud data might be being used. If not, then it’s just a flaw in the detection. If it is, then changing the setting to local only and a manual rescan might fix it.
