Additional discount products

Hello. Today I had a problem on opecart 3.0.3.2. Many products appeared with a discount that has not been established by us. I cleared the cache and everything returned to normal.
The site is not cracked, because the current files were checked with those from the backup
Where could this problem have come from?

That doesn't follow I'm afraid, your site probably has been compromised. You should get an experienced developer to investigate.

Could be many reasons. Perhaps giving more details, such what sort of discount, what cache you cleared and what extensions you are using mat make things clearer.
