Can't choose uploaded images when creating post / collection

so I’ve followed your instructions on Youtube to create posts using collections. I’m creating one now and it all makes sense apart from when I add an image. I click ‘select an image’ and the only option is to choose from my computer, not from images I have already uploaded! This can’t be right?


For now that’s the only way + pasting the link directly. Since it’s 3rd-party editor, we need to create plugin which will allow that.
