Deleted 800 NEF files... but no space was cleared on the clous

I just recently ran out of space on the cloud (which is what I use). Since I'm out of space, I went through one of my old shoots and deleted about 800 RAW files, but now it's showing that absolutely no space was cleared up. I'm stumped. Anyone know how to fix this? I thought it might be because of the smart previews, but I can't even find them on the cloud to delete them now.
