Every time I click "Save" for the amount of feedback that I've given to scanner for Laziza AI, it says that it's reached completion 100%, but after a short time, it always drops down. How is that possible?

This could happen because the system was removing or updating existing statements in the scanner instead of adding new ones, which made the progress appear to decrease.

Basically speaking, this is expected behaviour: every day the older learnings get outdated and they need to submit more feedback to keep scanner updated.
