Alignment "none" still wraps text

hi, when i insert an image into my post and mark it as alignment “none”, the text I write in the next line wraps aroun it instead of breaking. this only happens when the image is smaller than the full width of the post, so if i insert an image that is small but i want it to stand alone, i can’t–the text wraps around it!!

it was happening to me on this post: https://masteremergencyarchitecture.com/2011/haiti-building-back-better/
although you cannot see it because i enlarged the images so that it wouldn’t happen.

must be in my css but im not sure what to change as i don’t want to mess up the align left (im guessing that’s what i have to change??).

many thx!!
