iCloud storage showing data for Pages but no documents are saved - what is it?

In my iCloud storage it says that just over 100kb are being used by Pages. I used to use Pages a while back but never saved anything to iCloud drive. On checking iCloud drive there were no documents in there. I'm confused about what data Pages is saving to my iCloud - I know it is a very small amount of memory taken up but just wanted to know if anyone knows what might be saved in there and if it safe to delete it. There is also around 20kb taken up by iCloud drive - other documents, no idea what this is either. As seen in the screenshots below there are no documents in either section - just 'data' - whatever that is.
