Deleted CloudKit records Reappear

I'm building an iOS application using CloudKit.

It should allow a user to add, edit and delete Products in the cloud. The user can organize these in Folders. These folders are just other Record Types in cloudkit. There is no limit to the levels of folder the user can use, as any folder can just hold a CKReference to it's parent Folder. All CloudKit communication in my app happens in a dedicated CloudKitController Class

This all works, but stops working after a while for no clear reason.

When I test my app, I don't even user folders that are multiple levels deep. However, after using it a while (up to a week), All deleted records seem to reappear on CloudKit. A couple of notes on this:

- When I reset my CloudKit dashboard and start all over again, it works perfect. No code changes made.
- Obviously, I'm constantly editing my code as the app is in development. However, I generally don't edit the data types in my code that are to be stored in CloudKit. When I do, this issue does not arise straight afterwards
- Changes in the CloudKit Dashboard (e.g. adding data types) do not cause this issue
-Am not storing any records locally, like in core data. They just sit in a singleton as long as I use them
- When I go to CloudKit Dashboard, the Product Record Type shows it has e.g. 13 instances. Sometimes it's so bad, that my app actually loads over 100. I can also see them when I go to the recordZone, but still the RecordType says it only has 13 instances
- Deleting these records in CloudKit Dashboard only makes them disappear for a while. When I reload the page, they pop up again.

It has been going like this for a while now, and I have checked my code, the Apple Library and google numerous of times but I cannot figure out what causes this issue. I already filed a bug at apple, but no result yet either. Any response or solution would be highly appreciated
