Notability takes almost 3 gb of storage in documents

Hey Notability!

Can you guys explain how does my 37 files takes up to almost 3 gb of storage in my ipad even though Notability Cloud is there?

I have been using Notability since 2022 and never this much storage have been taking from you guys and I had way more notes than that?

Even when I delete files from both the notes and recently delete the storage stays the same or even go up?

As a context, I have an iPad Air 5 with the the earliest update of PadOS and update 16.5.3 of Notability.

Thanks
