Im guessing they come off the same Distribution Point. Probably a data issue in openreach.
Let me just expand on that for the OP...
The DSL checker needs more than the cab identity to estimate your FTTC speed, but it doesn't know your distance. Instead, it needs to know the signal loss between the cabinet and the DP (the connection box usually found at the top of a pole or in a footway chamber). If this piece of data isn't correct in the database, then the checker defaults to a "too long" result.
The likelihood in this case is that the Openreach database that records this data is incomplete or incorrect. For some people, we've seen the records for an individual property get the DP identity wrong, and for some people (incl me), the records get the cab identity wrong. As you have a block of properties affected, the best guess would be that you share a common DP, depending on the same piece of incorrect data.
As @witchunt suggests, reporting this via the CEO of Openreach might help, or the chairman of BT Group.
