Notes storage

My storage for notes keeps increasing instead of decreasing. Earlier today I had ~5.5 GB in notes but since I deleted around 20 notes with attachments, it’s only gone up. It was 20 GB today and now it’s 38 and it keeps fluctuating without me altering anything

How do I make it actually go down? I deleted all the files in the recently deleted folder too and restarting the phone, nothing helps
