Insane Adobe scan app size growth

I've just used Adobe scan mobile app (redmi note 😎 to scan 368 pages, having enough memory on my device. While cropping images afterwards I received system message, which said, I was running out of memory. I deleted 5+ Gb of apps and other data, so I could continue, but then the system message appeared again. When I looked at app data, Adobe scan got 9+ Gb growth. I totally don't get it, why has it become so large? Yesterday I scanned three other separate docs with 300+ pages combined and didn't have such issues, having even less device memory. After all, there no drafts left, I couldn't even save the photos, three hours of work in vain
