Twitter says it is a "bug accessible through a technical workaround" and the company is currently working on a fix for it.
Twitter's Instagram Stories-like feature, Fleets, starts rolling out for all users globally: How it works
Twitter first announced this feature in March and then started testing Fleets in Brazil, India, Italy, and Sounth Korea in June.
Twitter's new feature, Fleet, does not allow users to reply, retweet or like publicly.
People can respond to them, but the replies show up as direct messages to the original tweeter, not as a public response.
