However, the document states that "there is no defect identified in relation to the use of this product", which would contradict the Twitter post, so maybe it's a different product or either the poster or the document is wrong.
No, they (the manufacturer) are saying that users might "inadvertently" enter and confirm an incorrect value, which is not the same as the users enters one value but a bug causes it to be parsed, displayed and confirmed as a different value. The latter is what the Tweet claimed. Very confusing.
Also, why would you ever post about a potentially dangerous bug in a medical device without naming it? That just seems ... oddly sensational, to me.
They're saying that since there is a confirmation screen, it's the user's responsibility to catch the bug.
