Mysterious 518 Messages in iCloud: Hidden Second Trash or Bug?

I've noticed a peculiar issue with my iCloud account. Despite regularly deleting messages and emptying the trash, I consistently have 518 messages in iCloud that occupy space but aren't visible anywhere in my account. Here's what I've observed: 1. This number (518) remains constant month after month. 2. I've tried deleting all messages and emptying the trash. 3. I changed the setting from "Keep for 30 days" to "Keep for 1 year" to force the old deletion pop-up. 4. I've monitored the number of messages for several months, always returning to 518. My theory is that there might be a second, hidden trash in iCloud for data recovery after deleting from the system trash. The process would be: App > Trash > iCloud (hidden) > Permanent deletion after 30 days Has anyone else experienced this? Do you know how to reset this to zero? Would disabling Messages in iCloud completely or using a web option help? Any insights or solutions would be greatly appreciated!
