How to remove duplicate presets from cloud sync.

When i download the AME presets via cloud sync i get many duplicate presets. Every preset show up in the list at least 10 times. When i remove all settings, then upload, and then download the same thing happens.

How can i delete presets that are already stored in my cloud?

And if it's not possible can i somehow delete all presets or initialize the preset storage in my cloud?

Thanks in advance.
