PS Express Autosave to Projects

Hi, 

Every time I edit a photo in Photoshop Express, it automatically saves a copy to the "projects" file. This is entirely unnecessary as the photo is already saved under the main edit file, so it's simply a duplicate I don't need or want.

Is there a way to turn this unwanted feature off? 
It seems like an underhanded way to fill up my storage space so i have to buy more, which is super annoying and bad business. 
As of now I'm going in and deleting the extra photos but that's a pain as well and I'd rather not have to deal with it since, again, not something I need, want or asked for.
