25A and 25B Address Block Issues - City or Town missing values

25B has introduced many address block issue but a show stopper is that candidate is unable to find a City or Town and they are not able to submit if it is not in the list.

Some examples of missing towns in the address list:

Benson, Oxfordshire (postcode e.g. OX10 6ND)

Cholsey, Oxfordshire (postcode e.g. OX10 9LW)

Southwick, West Sussex (postcode e.g. BN42 4GJ)

Is there a way to either improve the list or switch off ?

We have only submitted 3 examples but there are no doubt many more.

Please advise, thank you and regards, Bea
