I checked my list just now and didn't have any problems. Did you press the right edit button? There's two that are on lists. One edits your review on the manga page and one edits your review in the list.
nvm ;-; I figured out that you can't have the list be full (meaning having 200) when editing the reviews and order
I figured it out, but thank you for taking the time to ask ;u;
Happy you figured it out! I actually didn't know you couldn't move things around when the list is full so this was great info for me too!
I started making lists for myself, but since some of the manga aren't ones I've read yet, I didn't add a review when I entered them into the list. When I tried to go in and add/change the review and change what order it is in, nothing changed. Any insight of what I might be doing wrong or if this a known bug?
