My iPhone says that my Notes is taking up 1.79 GB of storage. I only have 3 notes, and there isn't a lot of text in them. How do I fix this?

Recently there were a lot of notes on my phone, but I deleted most of them until there were only three notes left. However, my phone still says my Notes takes up 1.79 GB. I tried writing a really lengthy note to see if the GB would go higher, but it didn't change. I don't want to delete my three remaining notes, which have very little text in them. I doubt that these notes are taking up 1.79 GB. What is the problem here, and how do I fix it?

Restart your phone or at the very least fully close all windows and open settings again. The issue should self-correct with a refresh.

Restart your phone.

They were still kept in DUMP folder after clicking delete. You need to Empty the dump to get back the storage.
